Comment 1 Warren Togami 2004-08-27 03:26:17 EDT
This is a kernel, perhaps ACPI problem.  Can you please provide more
technical specifications about your laptop's chipset, processor,
video, etc.
Comment 2 Jeffrey C. Ollie 2004-08-27 09:28:31 EDT
Processor: Intel Pentium 4 M 2.2Ghz
Chipset: Intel 845 Brookdale
Video: ATI Radeon Mobility M7 LW
Ram: 1GB

Also, I forgot to note that this problem did not occur on 8/25/04,
only after I installed latest rawhide updates from 8/26/04.  SELinux
is disabled as well.

I noticed that there is a BIOS upgrade from HP for the notebook.  I'm
going to give that a try but I have to boot from the Windows XP
partition to install it.
Comment 3 Jeffrey C. Ollie 2004-08-27 09:59:42 EDT
Upgrading the BIOS from F.1D to F.23 and did not fix the problem. 
Going to try and upgrade to rawhide from 8/27/04 to see if that helps.
Comment 4 Jeffrey C. Ollie 2004-08-27 11:40:50 EDT
I upgraded to rawhide as of 8/27/04 and the problem persists.  I also
tried booting into kernel-2.6.8-1.524 and had the same problem.

Hmmm... Running the following command, even as a normal user causes my
laptop to reset:

cat /proc/acpi/battery/C132/state
Comment 7 Jeffrey C. Ollie 2004-08-27 12:20:20 EDT
I also tried the command from a text console to see if I was missing a
kernel oops or something but no luck.  A few seconds after you run the
command the laptop resets, no oops message, no nothin'.
Comment 8 Jeffrey C. Ollie 2004-08-27 12:34:04 EDT
I tried replacing the battery with a battery from a co-worker's laptop
- same problem.
Comment 9 Jeffrey C. Ollie 2004-08-29 15:50:04 EDT
I've now tried with these kernels:


and all will reset the laptop shortly after accessing

I also booted into Windows XP Professional (completely updated except
for SP2) and was able to use XP's battery status panel without any

Red Hat does not have the time resources to investigate your problem.
 You should go directly to the authors of ACPI on the acpi-devel
mailing list.  Reference this existing report when you report your

Plenty of details here.

Cleaning up this bug... was resolved with later versions... plus I no longer
have access to the specific laptop that was having the problem.
