2.5.70-bk16 - nfs interferes with s4bios suspend

2.5.70-bk16 - nfs interferes with s4bios suspend

[CaT]

Not too sure which list to send this to exactly so here goes. I go
my laptop back from warranty repair and it was returned with an old
version of the bios that still had suspend-2-disk capability in it.
Having set everything up I hit the suspend button and all seemed to
go ok upto a point:

=mutt entered refrigerator
=mutt entered refrigerator
=mutt entered refrigerator
=mutt entered refrigerator
=mutt entered refrigerator

Suspend failed: Not all processes stopped!

then it kept unfreezing my tasks till the following debug stuff 
came up:

Laptop seems to be working fine still. X and networking are going ok. The
nfs mounts still function (laptop is a client with 3 nfs mounts).

NFS needs "refrigerator" support for 
its kernel threads.

I didn't have any actual nfs mounts at the time but I tried it
with an otherwise similar system. It went through, got to freeing
memory, showed me a bunch of fullstops being drawn and then went
into an endless BUG loop. All I could pick out (after many a moment
of staring) was 'schedule in atmoic'.

I'll do a proper test with a console cable present in a few days. I
can't atm cos I'm not on the same network and don't have a 2nd 
computer to hook up the null-modem cable to.

Pre-empt is on btw.

I tested swsusp ex 2.5 BK tree - it is is broken. 

Looks something like: Writing data to swap (2273 pages): .<3>bad: scheduling while atomic!
and call traces.

Have a look at the thread on LKML around June 4: 
IDE Power Management (Was: software suspend in 2.5.70-mm3)

I'll wait for Nigel's 2.5 port

Turn it off. You don't want to debug preempt and nfs at the same time.

Was able to capture the output for this case (it's long). The result
without preempt is below this one.

Okay, you hit some ide problems, but freezing NFS worked okay. Did you
have active NFS mounts at this point?

Yup. I upgraded to .72 and tried again (using the new taskfile stuff) and
this time it suspended. On resume though, the framebuffer console wasn't
really functioning. I had to switch to X and then switch back again before
it was all groovy.

Ponderance: Why did it do a full s/w suspend when I asked for the bios
to handle it? I have s4bios showing up in /proc/acpi/sleep and the bios
is set to suspend to disk. I've even got an a0 partition fully formatted
and it still ignored it all.

I was using the following line to activate it:

echo 4b >/proc/acpi/sleep

I don't know, try looking at drivers/acpi/sleep/main.c, and if
neccessary insert some printk()s to see what's going on.

I've had a wee look into it and if I remove software suspend from the
compile, I get no sleep states at all. period. /proc/acpi/sleep does
not exist and nothing is reported in dmesg.

Now I had a look in drivers/acpi/sleep and in the proc.c file I found
this bit of code:

...
        state = simple_strtoul(state_string, NULL, 0);

        if (state < 1 || state > 4)
                goto Done;

        if (!sleep_states[state])
                goto Done;

#ifdef CONFIG_SOFTWARE_SUSPEND
        if (state == 4) {
                software_suspend();
                goto Done;
        }
#endif  
        status = acpi_suspend(state);
...

To me this appears to indicate that it's treating a request for a
sleep state of 4 (s/w suspend) and 4b (bios suspend) as the same thing
as simple_strtoul will stop at the b and return 4 and there are no
further checks being done. In a small experiment I added a test of
state_string[1] == 'b', recompiled and tried it again. It did not go
into s/w suspend as expected but it failed to do a suspend alltogether.

At this point I'm slightly lost. To me it's obvious that there's
something whacky with acpi_suspend() or something it calls but I'm
not sure what. :/

If you have 2.4.X, get 2.5.72. That should have
do_suspend_lowlevel_s4bios in wakeup.S. Look around and fix it so that
it is called when user does echo 4b. It may well be broken.

Been using 2.5.x all this time. Just did the following mod on 2.5.72-bk3:

#ifdef CONFIG_SOFTWARE_SUSPEND
        if (state == 4) {
                if (state_string[1] == 'b') {
                        do_suspend_lowlevel_s4bios(0);
                } else {
                        software_suspend();
                }
                goto Done;
        }
#endif  

And it activated bios suspend just fine. It didn't resume properly though.
The bios resume screen was left behind and the whole setup hung. I've
been using the suspend2disk functionality of this laptop under apm and 2.4.x
just fine (for months really - I rarely 'rebooted' my laptop) so I don't
think it's the bios that's b0rked.

And did you use S4bios with 2.4.X? apm and acpi are really different.

Modification you did is wrong; I'd try

#ifdef CONFIG_SOFTWARE_SUSPEND
        if ((state == 4) && (state_string[1] != 'b')) {
	        software_suspend();
                goto Done;
        }
#endif  

Does s3 work for you? s3 and s4bios should be really similar.

No. Never really used acpi under 2.4.x cos it all seemed like a bit mess
to me and the couple of times I tried it it just didn't do much of anything.
apm worked so I stuck with it. When I moved to 2.5.x I decided to test-run
as much as possible and so started using acpi.

As a note: at least the screen displayed and the requirements from the 
bios are both thesame when apm and acpi are used.

I had that in my original testing. It hung. I'll try again and tell
you where.

Haven't tried s3. Will do so asap.

Well I went the brute force way:

        /*
#ifdef CONFIG_SOFTWARE_SUSPEND
        if (state == 4) {
                software_suspend();
                goto Done;
        }
#endif
        */

Since it's h/w suspend I cared about, I didn't think it was important
to retain sw suspend.

> Does s3 work for you? s3 and s4bios should be really similar.

No. They both die in similar and different ways. :) s3 suspends to ram
(ie laptop goes sleepies) but on resume the kernel is totally hung. s4b
completely fails to suspend and the kernel doesn't like accepting input.
It still functions as the mouse generates synaptics errors and there's
continuous error output re eth0 but otherwise it's a dead duck.

Here is the console output for s3 and s4bios under 2.5.73-bk8:
