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.
