It crashes when SSHD starts, the serial console GETTY hasn't
started up yet so I can't even log in to run those commands

All I can do now is bisect and then try to figure out what about the

This is on a 64-cpu sparc64 box, and fast cmpxchg local is not set, so
maybe it's one of the locking changes.
