	reboot causes the system to panic.


	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 ;-/

	reboot; or shutdown -r
	Workaround: use halt and ctrl-Amiga-Amiga afterwards.
