>Description:
	This box is a dual processor machine with MP kernel.

	Machine had locked hard on the reboot several times. Normally
	I was in X, but once on text console and got this:

	panic: SA VP 208.2 is in state 7, not running or sleeping

	stopped in pid 208.1 (mysqld) at cpu_Debugger+0x4: leave
	db{0}> t
	cpu_Debugger()
	panic()
	sa_vp_repossess()
	sa_upcall_userret()
	syscall_plain(2b, 2b, 2b, 2b, 0)
	db{0}> reboot
	syncing disks ...

	Then it sits here and never does anything further.
	Info handwritten, that's why it doesn't contain the arguments.
>How-To-Repeat:
	run mysqld recompiled to use our native pthreads rather
	than mit-pthreads
	reboot machine frequently
	get panic on almost every reboot
>Fix:
	Sorry, don't know. Let me know if I can gather some useful
	info next time.
