I get the same panic (I think) in an evbarm/IQ80321 (GENERIC+LOCKDEBUG)
with 2006/05/29 sources.  I can reliably reproduce it with just:

	cd .../src/regress/lib/libc/ieeefp/except
	make regress

and that gets:

	sched_lock lock held

	lock heldlock: 0xc050db84, currently at: ../../../../kern/subr_pool.c:907
	last locked: ../../../../kern/kern_sig.c:1144
