[-- Attachment #1 --] 22:13:~$ uname -a FreeBSD mkushnir.mooo.com 11.0-CURRENT FreeBSD 11.0-CURRENT #3 r281432: Sun Apr 12 01:35:34 EEST 2015 root@:/work/obj/work/src.svn/sys/MAREK amd64 Went kernel panic twice today when trying to load vmm. Never seen this before (the previous kernel was built out of r278973, Feb 19 2015, was doing well). The panic is not reliable in the sense I could not reproduce it at will just loading/unloading vmm. I regularly work in my bhyve guests, sometimes swap between vmm and vboxdrv, all my scenarios haven't changed from the previous Feb kernel. Except that I re-built my today panicking kernel extending the MINIMAL config (including what I need) as opposed to the previous one "reducing" GENERIC (excluding what I don't need). Both today panic's back traces look identical. Attaching core.txt.1 (the latter one) and the output of "sysctl kern.conftxt". Let me know if someone wants to debug it. Thanks, Markiyan.
