current crashing VBox 6.1.16

[Karel Gardas]

Hello,

I'm trying to follow current installed in VBox VM. The VM is created 
with default configuration of 6.1.x suggested
for 64bit FreeBSD. The RAM is set to 32GB and CPUs to 12 cores. Te host 
is running ubuntu 20.04.x.

Anyway, while running 'make -j12 buildworld' the VM crash with following 
information in the VBox log:


00:02:26.650587 PIIX3 IDE: guest issued command 0xca while controller busy
00:02:26.652335 PIIX3 IDE: guest issued command 0xca while controller busy

00:02:26.653262
00:02:26.653286 I/O state inconsistent: state=0 request=1


Now, the question is if FBSD is allowed to issue command 0xca while 
controller is busy or if this is something which it should not do.

Thanks,
Karel
