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
