I tried the patch, it still crashes with the same oops. However, I tried
something I hadn't tried before which may shed some light on this. I
rebooted the system into UP mode, loaded the UP modules, and did the
mount of the file system. This time, no oops. It still doesn't work, but
the machine lives. The mount process simply hangs. When I go to another
terminal and kill the mount process, this appears in the syslog:

lock_gulm: ERROR cm_login failed. -512
lock_gulm: ERROR Got a -512 trying to start the threads.
lock_gulm: fsid=hopkins:gfs01: Exiting gulm_mount with errors -512
GFS: can't mount proto = lock_gulm, table = hopkins:gfs01, hostdata =

So, does that shed some light onto things? Something specific to SMP and
lock_gulm. It still doesn't work in UP mode, but it does not oops.
