I do not trust either of those backtraces. There is no way to get from do_nmi to do_exit. The presence of "unknown" entries indicates that the cpu 0 back trace is bad. Also all the ebp pointers are suspect, they are way out of range for the task addresses. You could be looking at a stack overrun or just random corruption of kernel data.
If you can reproduce the problem, set KDBDEBUG=0xff and bt. That will debug kdb and produce a lot of output. Send it to me, although I suspect it will just prove that you have stack corruption.
