Hi!

Kernel 2.4.5 & ReiserFS umount-fix patch
2 CPU SMP, 1 Gb memory

During working on an NFS mounted drive ``/mnt/somewhere'' I got this
oops (multiple times, so it is reproducable).

Thanks in advance,
Gergely

ksymoops 2.4.1 on i686 2.4.5.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.5/ (default)
     -m /boot/System.map-2.4.5 (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.

Warning (compare_maps): mismatch on symbol partition_name  , ksyms_base says c01c4020, System.map says c0154160.  Ignoring ksyms_base entry
