2.4.20 + ACPI-20021212 - strange oops

2.4.20 + ACPI-20021212 - strange oops

[Karol Kozimor]

Hi,
I had this oops shortly after the system had started completely (i.e. the
gettys appeared). This has been the only occurence so far, I don't know how
to reproduce it. I'm using 2.4.20 with xfs, acpi-20021212, swsusp and
cpufreq patches. Here is the ksymoops output:

#v+
ksymoops 2.4.8 on i686 2.4.20-xfs-cpufreq-swsusp.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.20-xfs-cpufreq-swsusp/ (default)
     -m /usr/src/linux/System.map (default)

Warning: You did not tell me where to find symbol information.  I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc.  ksymoops -h explains the options.

My DSDT is at http://hell.org.pl/~sziwan/asus/dsdt.dsl, if anybody bothered
to look. The oops wasn't fatal to the kernel, but I wasn't really in the
mood of checking how far would it go, so I rebooted shortly after the
prompt. I hope this will be useful to somebody...
Best regards,
