Description Stefan Stanacar 2011-08-03 13:05:04 UTC
After the update to kernel-2.6.40-4.fc15.i686 the system fails to boot unless I pass acpi=off as boot parameter. This wasn't necessary with the previous kernel ( kernel- )

The last displayed messages resemble this: 

 input: Power Button as /devices/LNXSYSTM:00/device:00/PNP0C0C:00/input/input0
 ACPI: Power Button [PWRB]
 input: Sleep Button as /devices/LNXSYSTM:00/device:00/PNP0C0E:00/input/input1
 ACPI: Sleep Button [SLPB]
 input: Power Button as /devices/LNXSYSTM:00/LNXPWRBN:00/input/input2
 ACPI: Power Button [PWRF]

The system just hangs (ctrl+alt+del, caps lock, num lock not working, no other messages after those).  
It also fails if I use noapic as boot param; it only works if I use acpi=off.

Is this a regression or just a case of crappy motherboard ? The mainboard is Asus P4V8X-X with a Via P4X533 chipset.

I will attach smolt profile, dmesg for 2.6.38-8 and dmesg for 2.6.40-4 with acpi=off.

Comment 9 Chuck Ebbert 2011-08-22 19:20:57 UTC
That oops address is somewhere in the ACPI BIOS, i think.

Comment 10 Chuck Ebbert 2011-08-22 19:40:28 UTC
People reporting this bug have either:
 Intel(R) Pentium(R) D CPU 2.66GHz
 Intel(R) Pentium(R) 4 CPU 3.00GHz

Comment 11 Chuck Ebbert 2011-08-26 19:06:58 UTC
Disassembly of the oopsing code shows that it's not even really valid instructions. So the ACPI code just jumped to some invalid address.

Comment 12 Len Brown 2011-08-27 00:25:33 UTC
Would be great to know via serial console capture if all the failures
look like Adam's in comment 7/8, or if there are multiple failures here.

If we really are crashing under acpi_processor_get_power_info(),
then something in C-states is broken.

Do any of these (individual) cmdline params allow boot to succeed?


Adam, please attach the output from acpidump.

re: comment #10
actually comment #1 shows this:

CPU Model: Intel(R) Celeron(R) CPU 2.40GHz
CPU Family: 15
CPU Model Num: 4

but that is still a version of the P4.
Apparently these are all 32-bit processors, so we don't
have the option to try the x86_64 kernel.

Can this be reproduced with an upstream kernel.org kernel?

Presumably upstream 2.6.38.stable works, b/c FC15's
kernel- worked.

What about
3.0.0 (I assume that FC is using 2.6.40 as a synonym for this?)

BTW, unrelated to the cause of this bug report, but present in comment #3
Linux version 2.6.40-4.fc15.i686 

WARNING: at arch/x86/kernel/apm_32.c:908 apm_cpu_idle+0x42/0x251()
deprecated apm_cpu_idle will be deleted in 2012

I added that warning to 3.0 to let folks
know that CONFIG_APM_CPU_IDLE=y may not be what you want.
If you think you really do need it, I need to hear from you...

Comment 14 Adam K Kirchhoff 2011-08-27 00:59:16 UTC
It is my understanding that Fedora's 2.6.40 is some version of 3.0.*.  I can try 3.0.3 over the weekend, assuming NJ isn't completely washed away.

I will try those other kernel parameters as well when I get a chance.

Comment 15 Adam K Kirchhoff 2011-08-27 01:37:11 UTC

Each one let the machine boot.  It still crashed with:


Comment 16 Len Brown 2011-08-27 02:29:31 UTC
processor.nocst=1 worked -- yay, that's a big clue.

Using that param, please show the output from

grep . /sys/devices/system/cpu/cpu0/cpuidle/*/*

Also, if you can show that same output for the working
2.6.38 kernel, that would be helpful to compare
what the FADT does vs _CST.

It seems that acpi_processor_get_power_info_cst()
is bombing out, presumably in the evaluation of _CST itself.
That routine has not changed recently, so it must be something
funky in the actual AML/interpreter.

Unfortunately, the version of acpidump you used didn't
grab the dynamic tables where your _CST lives,
or they were not exported.
Can you attach the files from here?


If you don't see anything there w/ the latest kernel,
then go back to working 2.6.38 and they should be present there.

Comment 17 Adam K Kirchhoff 2011-08-27 12:22:49 UTC
On 2.6.40, /sys/devices/system/cpu/cpu0/ doesn't contain cpuidle on this machine...  There is also nothing under /sys/firmware/acpi/tables/dynamic/ on 2.6.40.

I will have to build a 2.6.38 kernel first as the previous version I have installed is a 2.6.35 F14 kernel.


Comment 18 Adam K Kirchhoff 2011-08-27 17:48:41 UTC
On /sys/firmware/acpi/tables/dynamic/ contains nothing and /sys/devices/system/cpu/cpu0/cpuidle does not exist either.

Comment 19 Josh Boyer 2011-10-10 19:45:24 UTC
Has anyone tried a 2.6.39 kernel as Len asked?  You might be able to use


to test with.  Bug 730007 is showing similar issues and thus far we only see it on particular Pentium 4 models.  If someone is willing to git bisect this on an afflicted machine, that would be very helpful.

Comment 20 Josh Boyer 2012-01-06 15:08:35 UTC
Matthew Garrett pointed me at a patch for a regression in ACPI yesterday.  I've started a scratch build with this patch applied.  Could those with an impacted machine please try this kernel when it finishes building and let us know the results?


Comment 21 Josh Boyer 2012-01-06 16:05:14 UTC
My apologies, I pasted the wrong link to the scratch build.  This is the one that should be tested:


Comment 22 Stefan Stanacar 2012-01-06 17:05:46 UTC
Unfortunately I can't test it anymore, I'm running F16 now, with 3.1.6-1.fc16.i686, and I still have to use processor.nocst=1...

The 2.6.41.x kernels are almost identical to the F16 3.1.x kernels.  They are both based on the 3.1.x stable series.  You should be able to install the kernel from the scratch build without issue.

While I too am now running F16, installing the kernel
and trying a boot indicates that there is still a panic 
with the backtrace indicating acpi issues, so I do not
think this is (yet) identified/fixed.

Comment 25 Stefan Stanacar 2012-01-09 09:07:52 UTC
Same here, nothing changed.

Comment 26 Dark Shenada 2012-01-13 17:56:31 UTC
One more test case on D865PERL got same result while boot.
(DMI: /D865PERL , BIOS RL86510A.86A.0061.P09.0308281850 08/28/2003)
P.S: P09, P15, P21 BIOS has same result.

After enable ACPI debug and enable early stage serial console then I got bad CST.

Hers is the combination can boot:
enable HT in BIOS, acpi=off (no HT, no ACPI)
disable HT, no kernel command (no HT, have ACPI)
enable HT, processor.nocst=1 (have HT, have ACPI)

assuming that the 2.6.42 (3.2) builds don't make any difference either ?

> assuming that the 2.6.42 (3.2) builds don't make any difference either ?

Running the F16 kernel 3.2.7-1 still requires processor.nocst=1
(crash otherwise).

Is there something specific in the F15 2.6.42 kernel builds
that was intended to fix this (i.e. is it worth getting a
F15 2.6.42 kernel to test?)

Comment 30 Dave Jones 2012-02-24 18:02:38 UTC
no.that's pretty much equivalent (as far as acpi is concerned).

Len, is there any hope for resolution on this, or shall we just start dmi blacklisting the affected systems ? There doesn't seem to be too many of them at least..

Comment 31 Josh Boyer 2012-02-24 18:11:30 UTC
From 730007 we know that whatever caused this issue showed up in 2.6.39-rc1.  What we haven't been able to do is find someone with an impacted machine that is willing to do a git bisect to figure out which commit changed things.

Ok, I'll bite(*).  I had been hoping someone else would do the
work (compiling a kernel on that old system can take many hours,
so I can usually only get one/two tests per day), but I'll see
if I can get any useful results from a git bisect.


(*) I think the term is you shamed me into it.... :-)

Matthew pointed me to:


That seems like a rather plausible fix for this.

My git bisect has completed, and seems to confirm that
the commit referenced in comment 33 is the commit that
caused the problems.

Excellent.  Thank you very much Gary.  I should have a scratch-build with the patch I referenced in just a bit for people to test out.

This new kernel works in my environment without
