Oops happened during kernel compile
Its not easyly reproducable but after third kernel kompilation i a raw
it appears...., the system doesn't survive

The Oops decoded(may be wrong):
root@larry:~# cat /mnt/smb/decoded.txt
ksymoops 2.4.8 on i686 2.5.70. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.5.70/ (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.
Error (regular_file): read_ksyms stat /proc/ksyms failed
No modules in ksyms, skipping objects
No ksyms, skipping lsmod
