Comment 2 Vladyslav V. Prodan 2022-06-22 22:46:20 UTC 
Virtual machine with 12.3-STABLE and 2GB RAM

It produces tests for assembling the kernel and the world.
After installing the new kernel and world, the commands were made:
sync
reboot.

After that I got a panic, a subsequent reboot and a text crashdump.
Comment 3 Vladyslav V. Prodan 2022-06-22 23:08:50 UTC 
(In reply to Vladislav V. Prodan from comment #2)

The VM is running on host with Windows 10 with Virtualbox 6.1.34.
The virtual machine is allocated 6 CPU core and 2 GB RAM.
Inside the virtual machine, the virtualbox-ose-additions-nox11-6.1.34 package is installed and the services are running:
vboxguest_enable
vboxservice_enable

Probably one of these two threads.  Looks like a virtualbox bug then:
