I'm tracking STABLE and generally I'm resyncing /usr/src every 1-2 weeks and I started having problems since about Oct. 5. Unfortunately I had no answer. The problem *seems* gone away after taking the following actions: - disable powerd (I had enabled it few days before the problem emerged) - getting new sources and doing a new buildworld - rebuilding some gnome ports (the "non usual" ones I was using when panics occurred) and all the gnome deamons (sysutils/hal etc.) - as the guy having a similar problem on 7 "solved" moving away from gnome I'm not sure about what has been the resolutive action (and even if I had no more panics, I'm not really sure that the problem could be considered solved!) I hope that it could help about your stability problem... regards Barbara
