Best regards to all and everyone. I just purchased a new RS480 (Radeon
XPress200)-based motherboard. It is a Sapphire Pure Performance
PP-A9RS480. Mine is equipped with an Athlon64 3200+. I am attaching
the output of lspci -v
When booting with kernels from 2.6.15-rc1 up (tested with 2.6.15-rc1,
2.6.15-rc5, 2.6.15 and 2.6.16-rc1), the boot process freezes after
displaying messages retated to registering io schedulers:
...
...
io scheduler noop registered
io scheduler anticipatory registered
io scheduler deadline registered
io scheduler cfq registered
There is no OOPS of any kind. The disk activity led remains on. With
both 2.6.14 and 2.6.14.6, boot regularly continues with:
Floppy drive(s): fd0 is 1.44M
FDC 0 is a post-1991 82077
loop: loaded (max 8 devices)
pktcdvd: v0.2.0a 2004-07-14 Jens Axboe (axboe@suse.de) and petero2@telia.com
nbd: registered device at major 43
...
...
I tried to enable all debug options in configure, but no new message
appears.
Important: I obtain the same result (frozen after "io scheduler cfq
registered") when booting with a 100MB netinst debian sid bootdisk,
downloaded last night. An older (9 month old) Ubuntu bootdisk boots
perfectly. Both cd's are AMD64-specific.
I will be very happy to provide any further info, or to make any
test. Please CC me in your answers if you can.

Can you please add `initcall_debug' to the kernel boot command line?
That'll tell us which function got stuck.

or, more often
APIC error on CPU0: 40(40)
I tried either to pass noapic, or to disable apic in bios, and the
kernel entered a slow process of testing and refusing all addresses of
my SCSI card (I tried both an Advansys and a NCR: the result has been
the same) and then eventually gave an oops in ifconfig. I haven't
photographed those messages, but I will do so if needed.

Thanks. That's probably more lines than we needed ;)
If you have a web server somewhere, just upload the .jpg file. Or send it

Oh dear. We have 394 funtions all called 'init()' in the kernel.
netfilter is a prime source.

OK, it looks like a PCI initcall went South. Can you please add this, then
when it hangs, record the last few lines then send us those, as well as the
output of `lspci -vx'?

Is this new behaviour? If so, are you able to pinpoint the latest kernel
which didn't have such problems?

I had also had the problem that my Shuttle ST20G5 (a RS480 IGP based
system) hung in pci_init. This was with one of the Fedora Rawhide
kernels, after reporting it Dave Jones fixed it cause the next rawhide
kernel worked again, maybe he could explain what it was, and where the
fix is (if it is the same thing, but it really looks like it).

That was due to us carrying one of the 'make the clock not tick
at twice the speed on ati chipsets' patches. Matthew Garrett's variant iirc.
It worked fine in .14, but caused havoc in .15+
I put it down to the problem being fixed in other ways upstream.

Heh. I think you mean s/fixed/worked around/.
The bugme tracking this, 3927, is a joyous muddle of patches,
patches to patches, workarounds, and dueling command line options.
I ported this patch,
http://www.ussg.iu.edu/hypermail/linux/kernel/0504.0/1625.html,
to 2.6.16-rc1 to fix my pain, but 1) it didn't work without the
disable_timer_pin_1 kernel option and, 2) I don't think it's a fix
so much as a workaround.

These lines appear at the end of the logfile:
pci_init: 10025950
pci_init: 10025a3f
pci_init: 1002437a
pci_init: 10024379
pci_init: 10024374
pci_init: 10024375
pci_init: 10024373
and 1002:4373 is the USB2 (EHCI) controller. I attach the output of
lspci -vx. Even with 2.6.14.6, I have problems with USB. It did not
work at all, then I downloaded the latest bios, and now, right after
boot, usb works OK. But after some time (possibly after the first APIC
error message), newly inserted USB disks are not detected anymore, and
I had one case in which a mounted disk was not accessible anymore.
I just bought the motherboard - I did not make too many tests.

The motherboard is new. With the previous motherboard (via k8t88
based), using the same processor and most of the same boards, I did
not have any of these problems.

OK, so it sounds like quirk_usb_disable_ehci() caused your machine to hang
with the old BIOS. That's fairly bad behaviour from the kernel, even
though the BIOS presumably had some problems.

Can you please gather some more details on this and prepare a new report?
The full demsg output, machine description, etc. It might be best to do
this via a new bugzilla.kernel.org record so we know where to find it.
Thanks.

It did not hang. When inserting USB disks, I got messages like:
ehci_hcd 0000:00:13.2: Unlink after no-IRQ? Controller is probably using the wrong IRQ.
usb 1-1: device not accepting address 2, error -110
and the usb-storage module was not loaded. But the kernel went on
working. After upgrading the BIOS, with the same kernel, the USB disk
was recognized. But I now notice that the log file, with both old and
new BIOS, contains these lines:
ehci_hcd 0000:00:13.2: BIOS handoff failed (160, 01010001)
ehci_hcd 0000:00:13.2: continuing after BIOS bug...
ehci_hcd 0000:00:13.2: new USB bus registered, assigned bus number 1
ehci_hcd 0000:00:13.2: irq 18, io mem 0xfe02b000
ehci_hcd 0000:00:13.2: USB 2.0 initialized, EHCI 1.00, driver 10 Dec 2004
(only, the IRQ number changed from 10 to 18 after changing BIOS)

I will try that. I saw on apic.c that APIC error 40 should mean
'received illegal vector,' but I have no clue about how to interpret
this.
I will now play a bit with BIOS USB parameters.

I filed bug #5935.
The BIOS contains 4 fields related to USB. In the 'Integrated
peripherals' menu:
USB EHCI Controller
Onchip USB Controller
Onchip USB KBC Controller
In the 'PnP/PCI configurations' menu:
Assign IRQ for USB
All four only allow a choice between enable/disable. As expected,
disabling the first one makes the 0000:00:13.2 pci device
disappear. This results in the completing of the boot process. I am
writing this from a working 2.6.15 kernel, and I can mount my USB hard
disk. It probably works in 1.1 mode.
I noticed that the new motherboard's USB device is OHCI-based, while
the previous one was UHCI-based. The OHCI driver was previously not
compiled in. EHCI was functional even without a working OHCI module
(in 2.6.14). Compiling in the OHCI driver has had no effect in the
boot hang with EHCI enabled - the machine still hangs, and the output
is identical.
Disabling the second field (Onchip USB Controller) makes all USB
devices disappear - boot is OK, but there is no usb activity at all.
The third field has no evident effect. This is true of the fourth one
too (the one about IRQ assignment). I saw no change in boot logs.
Complete dmesg output for the successful 2.6.15 boot with EHCI
disabled can be downloaded from http://www.fluido.as/files/dmesg.txt.

I think what happened is the "always run quirks" code got turned into
the default too early, before the EHCI "quirk" version of the handoff
code got checked against what most systems have been using for the past
several years.
I noticed at least one suspicous thing: it enables an SMI IRQ.
Even in cases when the boot firmware says it's not using EHCI ...
easy to imagine that causing hangage.
Maybe this time it'd help to tell your BIOS "yes, DO use USB".
Or, the attached patch might help. Please try both experiments.

[-- Attachment #2: ehci-handoff.patch --]
[-- Type: text/x-diff, Size: 7247 bytes --]
This moves the previously widely-used ehci-pci.c BIOS handoff
code into the pci-quirks.c file, replacing the less widely used
"early handoff" version that seems to cause problems lately.
One notable change: the "early handoff" version always enabled
an SMI IRQ ... and did so even if the pre-Linux code said it was
not using EHCI (and not expecting EHCI SMIs). Looks like a goof
in a workaround for some unknown BIOS version.
This merged version only forcibly enables those IRQs when pre-Linux
code says it's using EHCI. And now it always forces them off "just
in case".

I applied the patch. The three changes to the second file applied with
an offset of 6 lines (to 2.6.15 vanilla). Nothing changed: the booting
process hung at the same place, generating the same printout as
before. I have now booted the new kernel with EHCI disabled, and saved
the dmesg oputput to http://www.fluido.as/files/dmesg2.txt (here,
USB1.1 is active).
It is time for sleep for me. I will perform any new test tomorrow
morning.

Thanks for posting this, it fixes my EHCI + APIC error, and makes my
laptop work just fine.
Turns out that 2.6.14 worked for it, but 2.6.15 didn't. git bisect a
zillion times later narrowed it down to the usb early handoff stuff but
due to merge issues, it was tough to track down the exact patch.
For fun I tried this one on top of the latest -mm, and it works!
So, care to clean it up to make it feel better to you and send it to me
again so I can add it to my tree? I know the next SuSE kernel will need
it :)
thanks,

OK, here's a version with a Signed-Off-By; against current GIT.
I'm mildly surprised it helps that laptop, but not surprised that
it helps _some_ of those "ehci init goofs" cases. :)

[-- Type: text/x-diff, Size: 7297 bytes --]
This moves the previously widely-used ehci-pci.c BIOS handoff
code into the pci-quirks.c file, replacing the less widely used
"early handoff" version that seems to cause problems lately.
One notable change: the "early handoff" version always enabled
an SMI IRQ ... and did so even if the pre-Linux code said it was
not using EHCI (and not expecting EHCI SMIs). Looks like a goof
in a workaround for some unknown BIOS version.
This merged version only forcibly enables those IRQs when pre-Linux
code says it's using EHCI. And now it always forces them off "just
in case".

Time has passed without further mention of this problem. Today I took
some time to discover exactly where the boot process was hanging. I
found the place.
In drivers/usb/host/pci-quirks.c, in function quirk_usb_disable_ehci
(should start around line 211) there is a stanza that reads:
/* always say Linux will own the hardware
* by setting EHCI_USBLEGSUP_OS.
*/
pci_write_config_byte(pdev, offset + 3, 1);
On my sapphire athlon64 motherboard (see the thread for more details),
this call never returns (without generating any output). I commented
it out, and now the EHCI subsystem works OK (currently running
2.6.16rc2).
I do not know what the right patch should be.

Interesting ... feels like a BIOS problem. If you want to experiment,
there's a right bracket -- "}" -- immediately before that. Try moving
it right after that write, so that write_config_byte is covered by the
preceding "if LEGSUP_BIOS" test; or copying the much later "disable SMI"
clause into an "else" for that "if".

The first one would be useless - I inserted lots of printouts to find
out where the freeze took place, and I know that the
EHCI_USBLEGSUP_BIOS flag is on (cap is 0x10001). The value remains the
same after the 'spin till it hands it over' loop - so that this
printout appears:
0000:00:13.2 EHCI: BIOS handoff failed (BIOS bug ?)
About the second thing you suggest: do you refer to this call?
/* just in case, always disable EHCI SMIs */
pci_write_config_dword(pdev,
offset + EHCI_USBLEGCTLSTS,
0);
In my machine, the write takes place without apparent ill effects. If
I add it as an else clause to the "if LEGSUP_BIOS" test, it won't
execute, because the EHCI_USBLEGSUP_BIOS flag is on.
In case you need it: hcc_params is 0xa012.

If it printed that, then how is it possible that it hung _before_ printing
that message??? Your reports are not making any sense to me.
Maybe that whole "if" block that turns that SMI _on_ is the problem; it
was part of the "early handoff" code, which came from who knows where,
was clearly buggy, and was never widely used until recently. Enabling
the SMI seemed pretty dubious to me, but I suspect that some undescribed
buggy BIOS really does need it ... maybe whoever provided that "early"
handoff version could report what they were trying to do by enabling
the SMI?

I already wrote that I had commented out the line that caused the
hangup:
// pci_write_config_byte(pdev, offset + 3, 1);
After commenting out this line, the machine boots OK and EHCI works
fine. It does print the BIOS handoff failed message.
If I do not comment out the above line, the machine hangs, and,
obviously, no BIOS handoff failed message is printed.

Then if disabling that code which enables the SMI doesn't work,
you have only one real option other than telling your BIOS not
to support USB keyboards/mice/disks: replace your BIOS.
The reason it prints the BIOS handoff message is because you
completely disabled the handoff, so your BIOS still thinks it
owns that controller. Commenting out that line is not good.

Sapphire has no newer bios than the one I am using. But I am saying
that USB works with that line commented out. I tried a couple of USB
disks, a USB mouse and my palm pilot - all seem to work quite OK. No
angry messages.
