Description of problem:
After booting my dual PIII with ACPI enabled, the system kept freezing
for a minute or so at a time. I tried to get a MagicSysRq call trace
while the system was hung but I'm not sure if the trace I got really
was from when the system hung of if it was generated afterwards. The
same moment I hit the key the system started responding again. Also
I'm not sure if it's complete since the system hung before the text
finished scrolling and this time it was dead for good. Anyway, I'm
attaching it here. 
If booting with the option acpi=off there are no problems at all. 

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. boot without acpi=off

goes away if you boot with "acpi=off"?

If you boot with ACPI enabled, but rmmod thermal
and rmmod processor, does it go away?

Does /proc/interrupts show a bunch of acpi interrupts
after the failure?

Comment 3 David Juran 2004-11-20 11:55:24 UTC
I have no such modules as thermal or processor, I believe the they are
compiled into the kernel. Also I the acpi interrupt count is still 0
after such a failure.

Comment 4 Dave Jones 2005-08-04 19:19:26 UTC
still a problem with the latest kernels ?

Comment 5 David Juran 2005-08-12 17:00:06 UTC
No, I can no longer reproduce this with kernel-smp-2.6.12-1.1398_FC4 (-:
