I just wanted to chime in and say I've had my 6.0-RELEASE #0 freeze up twic=
e
in the past few days. never once had it happen with 5.x. everything locks=
,
no keyboard response, no mouse, and after several minutes it reboots itself=
,
and savecore starts up during boot.. and again, it's not during heavy load=
,
both times i was running X, just browsing ye olde internet with firefox,
some other apps running as per usual..
