Hi,

today I encountered the following oops in kernel 2.5.65. Looks like reiserfs
is involved in some way.

ksymoops 2.4.9 on i586 2.5.65.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.5.65/ (default)
     -m /boot/System.map-2.5.65 (specified)

Error (regular_file): read_ksyms stat /proc/ksyms failed
No modules in ksyms, skipping objects
No ksyms, skipping lsmod
Unable to handle kernel paging request at virtual address 80c3eed0
