Hello,

[I subscribed to the list, so no Cc:s are necessary.]

After some days of uptime, I always get an Oops in the kswapd. After that, there are some other Oopses (mostly "cannot handle Kernel page request", but also some other oopses). But as far as I can see, the kswapd is always the first Oops after the reboot.

This is what ksymoops tells me:

***
multimedia:/var/log# ksymoops <messages 
ksymoops 2.4.3 on i686 2.4.17.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.17/ (default)
     -m /boot/System.map-2.4.17 (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.

1 warning issued.  Results may not be reliable.
***

It happened using 2.4.14, 2.4.27 and one or two 2.4 versions I don't remember now. 

Does anybody know what this means?

If you need more diagnostics, tell me, and I'll try my best.

Thanks a lot,
Markus Schaber
