[1.] One line summary of the problem:
Kernel 2.4.x oops with reiserfs on kdeinit
[2.] Full description of the problem/report:
Oopses appears after updatedb scripts when loading KDE.
Updating/reinstalling kde, updating gcc, kernel, reiserfsprogs, recreating
reiser fs doesn't change situation. Replacing sda - same effect.
Switching to ext2 - no oopses detected.
Same problem was found described in other mailing lists.
[5.] Output of Oops..
There is series of oops, it is first:
ksymoops 2.4.0 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.
