oops when rebooting 2.5.40 in driverfs_remove_file

[Bjoern A. Zeeb]

Hi,

when rebooting 2.5.40 I get an Oops . Had to write it away by hand
because serial console only gave crap.

If you need any further information please let me know.

ksymoops 2.4.6 on i686 2.5.40.  Options used
     -v /usr/src/linux/vmlinux (specified)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.5.39/ (specified)
     -m /usr/src/linux/System.map (specified)
