When I first install kernel and reboot pci passthrough still works. However after I've done installworld and mergemaster -iU reboot and I get this error. In vm-bhyve log

acpidump: DSDT is corrupt

When I rollback to 12.0 everything works again? So clearly it's not a bios setting.
Comment 1 Maurizio 2022-06-09 13:49:20 UTC 
I have the same problem running
# uname -a
FreeBSD clover-nas2 13.1-RELEASE FreeBSD 13.1-RELEASE releng/13.1-n250148-fc952ac2212 GENERIC amd64
on a ASUS SABERTOOTH X79 motherboard.

# acpidump -t | grep DMAR
acpidump: DSDT is corrupt

Unfortunately pci passthrough doesn't work.
Comment 2 Oleg Sidorkin 2022-10-14 15:49:42 UTC 
Same problem with my old ASUS Z77/Intel 4770.
vm_disable_host_checks="yes" options in rc.conf disables these checks.
