Well, yes and no.  It cures the oops, and it almost boots.  It passes
all tests, and gets to where we start mounting things...

kjournald starting.  Commit interval 5 seconds
EXT3 FS on hdc1, internal journal
EXT3-fs: mounted filesystem with ordered data mode.

=====================================================
[ BUG: possible circular locking deadlock detected! ]
-----------------------------------------------------
mount/2545 is trying to acquire lock:
 (&ni->mrec_lock){--..}, at: [<b13d1563>] mutex_lock+0x8/0xa

...and deadlocks.

I'll try to find out what it hates.
