Do you see any files in /var/crash? If yes - then it's a kernel panic and you have the coredump. Please read this article and submit a PR. 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 ;) Regards, Sergey On 07.09.2015 19:35, Niklaas Baudet von Gersdorff wrote: > On 02/09/15 21:32, Kozlov Sergey wrote: > >> Anyways, any userspace program should not be able to crash the kernel, >> so if you don't use self-modified OS and you're sure that everything is >> ok with your hardware, you should really consider adding a bug to >> > How can I debug this? > > So far I had a look at `/var/log/messages` of the jail and the jail's > host but both do not disclose anything special. > > Please see the files attached.
