The update was quite unfortunate as system became very unstable: it just hangs few times a day and panics sometimes. Some things can be reproduced, some cannot. Reproducible ones: 1. background fsck always makes system hang 2. system crashes on operations with nullfs mounts (disabled that for now) The most annoying one is ffs_copyonwrite panic which I cannot reproduce. The thing is that if I will run 'startx' on it with some X apps it will panic just in few minutes. When I leave the box with nearly no stress (just use it as internet gateway for my laptop) it behaves a little better but will eventually crash in few hours anyway. The even more annoying thing is that when I cannot save the dump, because when the system boots and runs 'savecore' it leads to fss_copyonwrite panic as well. The panic happens when about 90% complete (as seem via ctrl-t). Any ideas how to debug and get rid of this issue? System arch is amd64. I don't know what other details could be useful.
