Hi,

Running kernel 2.4.21-rc2 and using reiserfs (built as module) on an IBM
X31 laptop. I have hit a kernel bug (as per subject line).

Decoded Oops follows:

ksymoops 2.4.8 on i686 2.4.21-rc2.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.21-rc2/ (default)
     -m /boot/System.map-2.4.21-rc2 (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.
