I got my DEBUG enabled kernel crashed with the attached test,
first it breaks system to ddb and an attempt to continue
ends up in ofw 'ok' prompt. Commenting out lines below helps.
locore.s:4795
#ifdef DEBUG
	tst	%g2
	tz	1		! tpc NULL? Panic
	tst	%i6
	tz	1		! %fp NULL? Panic
#endif

Howto:
cc 960513-1.s
a.out

I looked for some time around, and decided to share it with the list.
