Hi Volker, That is what I had thought. But I clearly remember, back in 6.x the dump would be written to swap, then on restart, geli would kick in before savedump , therefore obliterating anything saved from the previous session. I will need to retest this...luckily 7-STABLE has been rock solid and haven't experienced many crashes. btw, how do I trigger a panic manually? :D cheers, B _________________________ {Beto|Norberto|Numard} Meijome "A fanatic is one who can't change his mind and won't change the subject."
