[oops] 2.4.13 kswapd invalid operand: 0000 (same stackpage as 2.4.12i before)

[oops] 2.4.13 kswapd invalid operand: 0000 (same stackpage as 2.4.12i before)

[Andreas Busch]

Hi Rik,

I posted the [oops] 2.4.12+i kswapd invalid operand: 0000 on october 22nd.
That time I used the crypto patches and NVidia, but I couldn't
reproduce the problem. This time it's on 2.4.13 without cryptopatch
but with loaded NVidia-driver again, sorry.

The fascinating point is that it's the same stackpage again !

ksymoops 2.4.1 on i686 2.4.13.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.13/ (default)
     -m /boot/System.map-2.4.13 (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.
