Description David R. Bergstein 2021-03-19 23:46:19 UTC
I have been seeing this boot time crash on an intermittent basis on a 
virtualbox running FreeBSD-13.0-RC2.  The information below was extracted from a recent crash dump:

drb-freebsd-13.localdomain dumped core - see /var/crash/vmcore.4

Comment 1 Jethro Nederhof 2021-03-21 05:54:32 UTC
Also seeing this on a 14-CURRENT guest, using virtualbox-ose-additions 6.1.18 from pkg. Host is Windows 10 with VirtualBox Version 6.1.18 r142142 with both the VMSVGA and VBoxSVGA display adaptors if that matters.

Disabling vboxguest_load="YES" (and vboxservice_load) in rc.conf, if I boot fully and wait a bit, it seems to work okay about 50% of the time if I manually start it with:

$ sudo service vboxguest onestart

I can then onestart vboxservice and everything seems to work OK as expected.

The other 50% it goes straight to ddb with the same "Sleeping thread (tid ######, pid ###) owns a non-sleepable lock" error and stack trace as comment #1. So intermittent not just at boot-time.
Comment 2 David R. Bergstein 2021-03-23 10:47:31 UTC
Just had anther crash with the error above at boot time, this time on FreeBSD 13.0-RC3.
Comment 3 parv 2021-03-24 23:17:34 UTC
I can confirm that this happens in 12-STABLE (n232872-af0cea80104) too. Sometimes on reboot; other times from a cold boot.
Comment 4 parv 2021-03-25 21:07:58 UTC
On every (re)boot FreeBSD was seeing panic with (Windows host & VirtualBOx 6.1.18) vbox-ose-additions 6.1.18; then restarting by itself normally. Got tiring fast.

I have reverted to VirutalBox 5.2.44 on Windows; and to -additions-legacy on FreeBSD. Let me know please if something I could try with 6.1.18 version components.
