[This time I'm going to do something new: I'll send a series of messages with
individual regression entries CCed to the people involved in handling them in
replies to this message.  Let's see how this works, fingers crossed.  Thx. R.]

This message contains a list of some regressions from 2.6.24, for which there
are no fixes in the mainline I know of.  If any of them have been fixed already,
please let me know.

If you know of any other unresolved regressions from 2.6.24, please let me know
either and I'll add them to the list.  Also, please let me know if any of the
entries below are invalid.

This sounds very much like some module registered IO ports/memory and was 
then unloaded without unregistering them.

It's a bit hard to guess which module it is, though. The oops says "[last 
unloaded: parport]", so that's likely to be the area.

So I *suspect* this patch might be relevant. Bug apparently introduced in 
f63fd7e299ee13da071ecfce2b90b58c5e1562b1 ("parport_pc: detection for 
SuperIO IT87XX POST") by Petr Cvek.

Petr?

Last comment I saw from Soeren says it does not really hang. It waits
for 5-10 seconds sometimes before continuing. We are still trying to
narrow this down with max_cstate etc..

I should say that my laptop (Vaio) _hangs_ at boot (less than 10% of boots)
and this is the last message I see:

"ACPI: Processor [CPU1] (supports 8 throttling states)"

and it stays there "forever" (more than 1 or 2 minutes at least).

I am not using my laptop too much these days, and I thought this
bug had been solved because it didn't hang for the last week (but
I boot it once per day), however it hang last night (using some
post 2.6.25-rc7 kernel)

I have pictures of the screen while showing this last message at boot, 
should I post it somewhere or that is not necessary?.

The bug was not in 2.6.24. It was introduced a couple of days 
before 2.6.25-rc8 and the fix was the last commit added before rc8 was 
released.

Yep, it's still present... but I don't have no time to debug it. :(

Rhe proposed workaround: "noapictimer" and "hpet=force" works so far...
Maybe it's buggy/bad hardware after all and 2.6.24.4 just doesn't trigger it?!

If the sysrq key still works when that happens, try to do a sysrq-t,
s, b to generate a trace, sync the filesystem, and reboot. If anything
made it to the logs, please post it.

Yes it still is present in the mainline.

Sorry, didn't have time to fix it, since I have been busy with other stuff. 
Will have a look at it over the weekend.

Still present, active discussion in bugzilla. At least partly am-utils 
problem (actually there are 2 of them, one am-utils mount structure 
version problem, another NFS locking problem that was also uncoveredy by 
stricter checking in 2.6.25).

Yes. The machine resumes and display stays black using s2ram -f -p
(blindly typing reboot etc on keyboard does what is expected). However
display comes back on 2.6.24.

When you asked me just 2 days ago exactly the same question in the 
Bugzilla entry I immediately confirmed it's still present.

Was anything wrong with my answer (and the subsequent discussions) that 
you now also ask Toralf for confirmation?

Sysrq keys don't work when it hangs, I have to push the power button.

Another thing to notice is that when it happens, it usually happens
more times in a row (like 3 times). And then it can take many boots to
happen again.

I've uploaded the picture where it hangs, it is in the very beginning
of the boot process:

Actually this is 
http://bugzilla.kernel.org/show_bug.cgi?id=10117 ... and what you
describe is exactly what I was seeing. 

However I thought that we are talking about the hang with 
ladder governor as the last message on the screen. Anyway I am not sure
if both bugs are related or not but I couldn't reproduce the throttling
states bug with current mainstream...

Ops, I am sorry. But in the bug description which Rafael wrote above
there is a link to your original post

References: http://lkml.org/lkml/2008/2/23/263

so I thought this was the bug being dealt with here.

> However I thought that we are talking about the hang with

I thought that the bug had vanished, but two days ago it happened
again in my Vaio. There were a couple of different messages comparing
to the picture in the link above, but the last message was exactly the
same.

And I see that Rafael closed the bug 
http://bugzilla.kernel.org/show_bug.cgi?id=10117

The hang two days ago was with 2.6.25-rc7-00150-g(can't remember),
do you think the bug was fixed since that kernel?

I will try to test with the latest git, but I don't have internet
access at my house anymore, so I will have to clone the git
repository into my pendrive and take it there...

Probably still there, but it's not easily reproduceable
and doesn't happen more than once every couple of days or so.

Can you try the latest git and see whether this still is a problem?

Upgraded to 2.6.25-rc8-00139-ge315c12, the server is running 8 hours
already and it seems it's fixed.

Anyway, should such warnings be threated as regressions?

I've just updated to latest git, but it may take some time for it 
to happen again (the first 3 boots were okay). Last time it happened
with 2.6.25-rc7-00149-gaf8be4e (I checked now). 

Do you have reasons to believe this issue was fixed since then?

OK, I will apply it manually and test it.

For the record: yesterday my laptop hang at boot with v2.6.25-rc8-139-ge315c12

This seems to be a bug in am-utils:

	https://bugzilla.am-utils.org/show_bug.cgi?id=612

and while we try very hard to not break existing binaries that assume some 
old broken kernel behaviour, things like system setup code that is 
outright buggy is kind of exempt from that rule. So I think in this case 
it really is a user-level issue.

I wouldn't call this a regression. It's a hard-to-trigger warning that is 
being debugged.

I have a cleaner patchset prepared than the one that got bikeshed

I applied Venkatesh's patch from the link above on top of 
v2.6.25-rc8-139-ge315c12, but my laptop hung at the 11th boot with the
same state show here:
http://www.ift.unesp.br/users/crmafra/dsc04673.jpg

I waited 3'30" but the boot process never resumed, so I pressed
the power button.

Any further patches I might try?

First of all you try to get the tracking of all bugs into Bugzilla, and 
now you've sent a batch of emails where the answers will not get into 
Bugzilla automatically.

As an example, for the bug we are talking about the main value of you 
asking me in Bugzilla was not that I confirmed it's still present, the 
main value was that this caused Mauro to make a fix. What would have 
happened if Toralf had answered in an email that the bug is still 
present?

And especially for trickier stuff like suspend/resume problems it might 
also make sense to send the email to all people who might possibly be 
involved with the bug - even if this means putting all email addresses 
from 5 MAINTAINERS entries into one email. It takes a bit more time when 
writing the emails, but my experience was it's worth it.

Most probably, I would add a reference to his reply to the bugzilla entry.

Rafael, I added myself to bug 10117 instead of 10093.

I am sorry about this confusion, but the References: to
both bug 10093 and 10117 are this email from Soeren
http://lkml.org/lkml/2008/2/23/263 (and this is how I got
to this thread)

That is the hang which happens in my laptop with latest git.
You can check that by looking at this picture I took while
my laptop was hung http://www.ift.unesp.br/users/crmafra/dsc04673.jpg

However you closed bug 10117, but that is not fixed for me so I am 
going to reopen it if you don't mind.

By the way, thanks for all your effort to track down these regressions.

OK

Well, perhaps we should mark bug #10093 as a duplicate of bug #10117 or
vice versa.  Soeren, are they really different?

No idea... All I can tell is that I could not trigger the 
supports 8 throttling states hang anymore since quite a while... It
looks like it got harder to trigger for Carlos too... maybe he could try
to disable CONFIG_CPUIDLE and check if it is at least CPUIDLE related?

Carlos,

Hmm. So, we still have some bug hidden in there..
As this is similar to 10117, we should probably track this there.
10093 is a different cpuidle specific bug looks like, as it happens at a
different place while switching between governors.

Can you attach your kernel config, acpidump output and dmesg when kernel
boots ok to that bugzilla.
Also, if you can please try processor.max_cstate=2 boot option and see
whether you still can reproduce the problem. If you can, then try
processor.max_cstate=1. For this boot option to work, you have to have
ACPI_PROCESSOR built into your kernel (and should not be a module).

One more qn. Did you see this problem witj 2.6.24 as well or is this
something that you started seeing only recently?

Thanks,
VEnki

you could use what I've send as I was seeing this bug too... but maybe
his config (sony vaio?) is well directly point to the problem.

This thing I can answer: yes this is new in 2.6.25 and in there since at

I can add that on my laptop (toshiba U305, Intel 945GM chipset), s2ram
-f -p -m which used to work ok, in X and console, in 2.6.24 stopped to
work (I tested -rc8, but I think it's like that since a long time).
Machine resumes but the screen stays off after that, although machine is
working (exactly as Soeren said). 

On the other hand, now the plain "echo mem > /sys/power/state" works
perfectly, from X and console. So some of the magic vbe save/restore of
s2ram mess something up for this card. 

Is it a regression for my laptop (is evidently one for Soeren)? On one
side, a "used to work" setup is broken, but it worked with userspace
hacks; now it works with the plain way, and that's clearly better.

I added on Cc: Jesse, to whom I confirmed that Intel suspend/resume was
ok on Feb, 21, [1] and suspend-devel list, because now I do not know
what to do with the whitelist I sent for s2ram for this machine...

Your graphics adapter is different from the Soeren's one and the fact that
"echo mem > /sys/power/state" works for you now is probably a result of the
recent changes in the i915 driver that is now supposed to handle suspend
and resume.

That said, there had to be a change that affected both of your systems
between 2.6.24 and .25-rc8.  Moreover, I'm suspecting ACPI or something
generic in the DRM core.

As far as ACPI is concerned, one commit related to backlight has just been
reverted, so Soeren, can you please test the current Linus' tree?

I uploaded the kernel config and dmesg to the bugzilla a few minutes ago.
I don't have a copy of the acpidump with me right now (laptop is at home,
I am at the physics institute now), but if there is urgency you can look
at the acpidump I've sent here http://lkml.org/lkml/2008/2/11/364

It started more or less at the same time as 2.6.25-rc1 was released.
It was not there at 2.6.24.

Well, at first I thought it was related to drivers/acpi/thermal.c, because
the next kernel message (in a successfull boot) after the point in which it 
fails is

ACPI: LNXTHERM:01 is registered as thermal_zone0

and there were some changes to that file a bit before -rc1 was out.
For example, commits 3f655ef8 and ce44e19701.

I don't know if this is recommended, but I added Zhang Rui to the Cc: list
to exclude or confirm this possibility.

I tried to use vbetool to get my text console back with 2.6.24 after a
suspend to RAM. As a result, I got a text working console, but a
crashing X server sometimes after resume, and the only way to get X
back was to reboot.

With 2.6.25-rc, the text console is fine after resume, due to the
recent changes to the Intel i915 DRM driver. Maybe those people who
used to use vbetool prior to 2.6.25 should check if this is still
needed.

Yep, the problem is just that: in 2.6.24 vbetool hacks (in my case,
using s2ram -p -m options) was needed to resume graphics. Now they are
not needed anymore, and using them _break_ resume.

So, people with a working suspend-to-ram setup (even using the whitelist
in s2ram, I mean, simply calling s2ram) will discover that 2.6.25 break
their machine. Removing the s2ram package and suspending with
kernel-only machinery will work, but... well, it's not user-friendly.

The above holds only if you have an intel graphics adapter. For me
(radeon) it really breaks (as in echo mem >/sys/power/state leaves me a
black screen on resume and manually typing vbetool post or vbetool
vgamode simply hangs the machine).

For me (radeon X700) using binary fglrx xorg driver without the binary
kernel module (which does not compile under .25rc for me)
resume-from-ram works using s2ram.

Lightly tested with -rc8.

I am talking about console only. X is a completely different issue
especially with fglrx (which will very likely do the re-init).

The assumption that a static table of VBE-based quirks can be used 
without paying attention to the capabilities of the video driver has 
always been broken, though I'll freely admit that it's all my fault in

That said, running vbetool from the console after resuming into it with a new 
i915 driver shouldn't kill your machine...

Romano, you say this was working for you before with the suspend/resume 
enabled i915 driver, right?  So something else must have broken?

You can run the upstream DRM modules against 2.6.24 to insulate yourself from 
anything in 2.6.25 that might have broken things...  That would be a good 
data point.

I booted the laptop many times yesterday (to test these things):

1) CONFIG_CPUIDLE=n seems to help. It didn't hang after 17 boots

2) processor.max_cstate=2 doesn't help, it hung at the 10th boot

3) processor.max_cstate=1 survived 20 boots without hanging

And when it hung, it always stop at the same point shown in
the picture quoted above.

I hope this will help.

Could you get us any debugging output from s2ram? Or maybe even strace
it in both working and broken case, and comparing them? (You may want
to disable randomization so that results are comparable).

I did on 2.6.24

strace -ff s2ram >s2ram24.trace 2>&1

and .25

strace -ff s2ram >s2ram25.trace 2>&1

with the .24 bringing the display back and .25 not. Files are here

Hmm: 

/sys/bus/pci/devices/0000:00:1b.0/irq

contains 21 in one case and 22 in another... as do other
interrupts. Is that expected? Can you post /proc/interrupts for both
versions?

Hmm, big part of trace is:

vm86old(0xb7f76c8c)                     = -1 ENOSYS (Function not
implemented)
vm86old(0xb7f76c8c)                     = -1 ENOSYS (Function not
implemented)

...I wonder why we do it so many times?

And here's the difference. .25 says:

vm86old(0xb809ac8c)                     = -1 ENOSYS (Function not
implemented)
vm86old(0xb809ac8c)                     = -1 ENOSYS (Function not
implemented)
Error: something went wrong performing real mode call
open("/sys/class/graphics",
O_RDONLY|O_NONBLOCK|O_LARGEFILE|O_DIRECTORY|0x80000) = -1 ENOENT (No
such file or directory)
open("/dev/tty", O_RDWR|O_LARGEFILE)    = 6
ioctl(6, KDGKBTYPE, 0xbfae8887)         = 0

...can you perhaps add printf-s to s2ram to find out what changed?

It might be that configs are slightly different - if you think this
gives a clue I will post them, but your discovery below looks promising:

OK, I searched for "something went wrong performing real mode call" in
the s2ram source and found this function:

int do_real_post(unsigned pci_device)
{
    int error = 0;
    struct LRMI_regs r;
    memset(&r, 0, sizeof(r));

    /* Several machines seem to want the device that they're POSTing in
       here */
    r.eax = pci_device;

    /* 0xc000 is the video option ROM.  The init code for each
       option ROM is at 0x0003 - so jump to c000:0003 and start running
*/
    r.cs = 0xc000;
    r.ip = 0x0003;

    /* This is all heavily cargo culted but seems to work */
    r.edx = 0x80;
    r.ds = 0x0040;

    if (!LRMI_call(&r)) {
        fprintf(stderr,
            "Error: something went wrong performing real mode call\n");
        error = 1;
    }

    return error;
}

which is obviously called from

int do_post(void)
{
    struct pci_dev *p;
    unsigned int c;
    unsigned int pci_id;
    int error;

    pci_scan_bus(pacc);

    for (p = pacc->devices; p; p = p->next) {
        c = pci_read_word(p, PCI_CLASS_DEVICE);
        if (c == 0x300) {
            pci_id =
                (p->bus << 8) + (p->dev << 3) +
                (p->func & 0x7);
            error = do_real_post(pci_id);
            if (error != 0) {
                return error;
            }
        }
    }
    return 0;
}

so either the graphics adapter is somehow not ready yet or a wrong
address is used for posting?

Do you already now have an idea? Or which things should I print out?

Well, that looks suspiciously similar to

Hmmhh the only difference is that I don't have a core 2 duo but only a

should I see something like nx enabled in dmesg?

OK I tried noexec=off now... same error in s2ram ... so I guess my CPU

s2ram segfaulted in that bug, but your one desn't.  Still, we could have done
another thing that prevents s2ram from doing its job on your system.

Sweet, so the problem is inside X86EMU_exec(), right? ...and that's
bytecode interpretter. You could add printfs() all over it, to see
where the execution differs.

Or something goes wrong in the interpretter...

It starts to look like git bisect is the easier way to get some
results...

can you try if this patch to libx86 (make sure it gets installed and used...)
fixes the problem?

Especially the userspace stuff (VBE_*) should not interfere with the restoring
now done inside the kernel drivers.

for me it won't (core 1 duo), not clear whether his toshiba is a core 2
duo though supporting that flag...

anyway I tried again with the patch and 2.6.25 and same thing, display
stays black on console. then i s2ram'd again and - the display came
back!!

all my further attempts never made it come back... however from inside X
it works now (radeonhd...).

Hmmhh maybe when the radeon(hd) fb driver enters the kernel it will work
for me nicely again...

Sorry to be a bit though, but _what_ I'm supposed to patch? It's in
s2ram sources? Thanks!

Patch the sources of libx86... (s2ram makes use of that lib to do the
POSTing)
