2.3.99-pre3 oops in mount path

From: Scott Henry (scotty@rahul.net)

SMP dual Celeron, IDE, autofs, etc.

This oops happens when trying to mount or fsck a partition on the
second IDE disk (/dev/hdb).

ksymoops 2.3.3 on i686 2.3.99-pre3. Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.3.99-pre3/ (default)
     -m /boot/System.map-2.3.99-pre3 (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.
