>Description:
	reboot causes the system to panic.

	_Debugger(16aa4,a585c,1db9e9c,2,1db9e40)+6
	_panic(a585c,0,1bb9ed4,cded76,2)+34
	_panictrap(2,0,0,1db9ee8)+60
	_trap(2,0,0)+19a
	fault(?)
	_boot(0,dfffdb4,1db9fa8,a6442,54f900)+c
	_reboot(54f900,1db9f88,1db9f80)+26
	_syscall(37)+13a
	_trap0()+e

	halt does work.

	BTW, this also occured with 950710 kernel + few mid-august
	modules (grf_ul & friends, + the new sbic.c driver + M.
	Hitch's patches. Don't know about without M.Hitch's patches;
	that one panic()t to soon ;-/

>How-To-Repeat:
	reboot; or shutdown -r
>Fix:
	Workaround: use halt and ctrl-Amiga-Amiga afterwards.
