Got a new kernel oops. Same machine as the previous reported oops
in journal_try_to_free_buffers(). Something seems definately wrong
in 2.4.23.

Marcelo, I'll follow your suggestion te revert a particular change.

ksymoops 2.4.9 on i686 2.4.23-x91.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.23-x91/ (default)
     -m /boot/System.map-2.4.23-x91 (specified)
