PROBLEM: Strange oops

Hi,

I know, the subject isnt apropriate at all, but i dont know how to
describe it better. I got this two oopses with 5 minutes time
differences while i was working on my laptop.

I was downloading something and upgrading my system (apt-get upgrade) ie
was doing a lot of network traffic and working on the harddisk.

I dont think that the problem comes from the ext2 or the paging system
directly but is somehow related to the airo (cisco wireles card) driver
i use. This is also the thing where the tainting comes from, i had to
use the drivers from cisco directly because those of 2.4.20 crashed my
system everytime i created some network traffic. Otherwise it's a plain
vanilla 2.4.20 kernel.

Also something special about my system is that i dont have swap
activated (gave me other problems with the vm), but the 256MB are enough
for most i do.

The system i work on is a Thinkpad A21m (PIII 700) with a 2.4.20 kernel
and a Debian Sarge installed. The kernel was compiled with gcc 2.95.4
(Linux version 2.4.20 (root@kibako) (gcc version 2.95.4 20011002 (Debian
prerelease)) #1 Tue Mar 4 13:33:55 CET 2003)

The modules i had loaded were:
Module                  Size  Used by    Tainted: P  
ppp_deflate             2904   0  (autoclean)
zlib_inflate           18116   0  (autoclean) [ppp_deflate]
zlib_deflate           17368   0  (autoclean) [ppp_deflate]
bsd_comp                3928   0  (autoclean)
ppp_async               6400   1  (autoclean)
ppp_generic            16672   3  (autoclean) [ppp_deflate bsd_comp
ppp_async]
slhc                    4336   0  (autoclean) [ppp_generic]
cs46xx                 54384   2  (autoclean)
ac97_codec              9928   0  (autoclean) [cs46xx]
airo_cs                 3332   0  (unused)
airo                  101964   1  [airo_cs]

I also dont think that the problem comes from the hardware, as i have
this laptop now for a little more than 2 years and everything else
(mostly gcc and perl/shell stuff) works fine.

Due to some reasons i dont seem to be able to reproduce it :(

I know this bugreport (if you can call it like this) is very vague, but
maybe it helps.

Please CC me as i'm not subscribed to the mailinglist.

Thanks a lot for your work.

ksymoops 2.4.6 on i686 2.4.20.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.20/ (default)
     -m /boot/System.map-2.4.20 (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.
