Hardware error. I booted it and it failed somehow. I rebooted the old kernel 
and got a panic, then dumped the core, but it's the old kernel. I rebooted a 
third time and it failed to see the second drive. I turned it off, reseated 
connectors, rebooted, and now get a stream of "missing inode" errors 
alternating with something else I can't read.

How do I get out of this?

Finally it gave "page fault while in kernel mode". The error it was scrolling 
is frozen now. It says:

HAMMER: WARNING: Missing inode for dirent "7A7394EE65276"
	obj_id = 0000000b4ee65276, asof=ffffffffffffffff, lo=00010000

I tried to dump and it said:

Dumping 323 MB:spin_lock: 0xc341f3d8, indefinite wait (1 secs)!

I'm going to try to reboot to single-user mode.
