Description Taavi Burns 2004-03-19 11:14:17 UTC
Distribution: Gentoo Linux 
Hardware Environment: IBM Thinkpad T30 (2366-85U) 
1024MB RAM, 2x 40GB HD, Cisco Aironet 350 MiniPCI 
 
Software Environment: 
BIOS 2.06 (most recent) 
Embedded Controller 1.03 (most recent) 
 
Problem Description: 
The machine randomly locks up.  Frequency is between twice a day 
and once every two days.  I can't figure out what the lockups may 
have in common.  Nothing relevant seems to be written to 
/var/log/messages, as the lockups happen when the lid is open, 
closed, when I'm doing nothing, or when I'm moving the mouse. 
If I disable ACPI, the machine is relatively rock solid (over 
one week uptime). 
 
Diagnostic Information: 
http://hammerfell.dhs.org/acpidmp.out 
http://hammerfell.dhs.org/dmesg.out 
http://hammerfell.dhs.org/dmidecode.out 
http://hammerfell.dhs.org/lspci.out 
 
Steps to reproduce: 
Enable ACPI on a T30 for any 2.4 or 2.6 kernel. 
Wait until it freezes. 
 
Today I tried a vanilla 2.6.4 with the most recent ACPI 
patches (downloaded on 04-03-18) from acpi.sourceforge.net. 
It still freezes.

does pci=noacpi help? in addition, is Cisco Aironet 350 MiniPCI a PCMCIA card?
Comment 2 Len Brown 2004-03-24 18:18:43 UTC
please disable the processor driver and see if the machine becomes more stable.

thanks,
-Len

First try ACPI without the ACPI processor driver.  Thanks for the tip, Len!

Is pci=noacpi different than not compiling ACPI into the kernel?  If it is different, then no, I have not 
tried it.  I will do so and see what happens.

The Cisco Aironet 350 is a MiniPCI card, not PCMCIA.  The T30 has a MiniPCI slot accesible via a panel 
on the bottom of the laptop.  Support for this card was integrated in to kernel 2.6.3 (from patches by 
Fabrice Bellet) using the standard 
airo.ko driver.  It was previously a source of instability, though that no longer appears to be the case (as 
the laptop did not crash using the card for a week, when ACPI was not compiled into the kernel).

Since disabling the processor driver, the laptop has been stable for a 
few weeks!  Let me know if you need any debug work done to try to fix 
the hangs when the processor driver is enabled. 
 
Thanks!

if you disable Cisco Aironet 350 MiniPCI wireless card and load processor 
module, what is the result? I want to check if there is conflict between the 
card and processor driver. thanks.
Comment 6 Taavi Burns 2004-04-19 07:11:42 UTC
When things were crashing, my first thought was the Cisco MiniPCI card.  I 
physically removed it from the system, but the lockups continued to occur. 
I would have had the processor module compiled and loaded at that point.

any change in linux 2.6.10?
Comment 8 Adrian Bunk 2005-07-05 10:39:34 UTC
There was no answer to Len's question whether this problem is still present in
more recent kernels.

Please reopen this bug if it's still present in 2.6.13-rc1-mm1.
