https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D228768 --- Comment #2 from John Baldwin <jhb@FreeBSD.org> --- Hmm, I thought had sent a mail about this earlier, but I guess not. Are you able to put DDB in your kernel config and get a db> prompt at all? If so, a stack trace would be really helpful. If not, one thing to try first that m= ight help is to get down from 4 CPUs to 2 CPUs. You can set these hints at the loader prompt (or in loader.conf) to disable CPUs 2 and 3: hint.lapic.2.disabled=3D1 hint.lapic.3.disabled=3D1 --=20 You are receiving this mail because: You are the assignee for the bug.=
