I have the "LOCKDEBUG spl fix" in, and haven't seen a single xcall
message since.  (But I have LOCKDEBUG in too.)  I have had it freeze
up twice though.  Both times it was bad enough that the BLINK option
didn't blink the power light anymore.  The first time it was bad
enough that I couldn't get into DDB either...  Don't know what to
look for once I'm in DDB and I can't get a good dump either, since
everything always panic's at the end of a shutdown.
