The problem with a hard lock-up out of which you can't escape into the debugger is that it makes meaningful bug reports impossible. My non-SMP workstation has exhibited apparently arbitrary lock-ups since the advent of SMPng. I thought I was the only one, since my question on the freebsd-current mailing list went unanswered. From my understanding, John's WITNESS code allows us to break into the debugger from within interrupt context. If the lock-ups are happening in there, then this may help us provide better bug reports. Oh, and a couple of deep breaths are probably in order. :-) Ciao, Sheldon.
