Or isn't there something worth noticing because I don't have dumpdev configured? I'm afraid that I can't remember another change that I made to the jail that caused it to crash. But, up to now, the only thing I can remember I did was upgrading net/syncthing. > I know that it can be a difficult path to take, but please do that. > Having a kernel panic in a -RELEASE version is rare and your particular > circumstances are very valuable, cause you can reliably reproduce the bug. > > Don't be a free rider, make FreeBSD better ;) I definitely want to further investigate the problem and keep everyone updated about it. It's just that I need some help to do that, so your reply is very much appreciated. I'm definitely not a free rider. ;-) So far, I haven't started the jail again since it has continuously broken my system. (I'm scared.) I will configure dumpdev first and after that I'll start the jail. I'll keep you updated.
