I had a similar issue after upgrading 12.1-RELEASE to 12.2-RELEASE using freebsd-update It would boot to a mountroot prompt more times than not, you can just hit the return key at the mountroot and it will reboot I did try upgrading the motherboard (AsRock) BIOS and the bootcode using zpool upgrade zroot but this did not help - in my case value 1 is efi and value 2 is freebsd-boot so used 2 What did fix it was going into BIOS setup and changing the first boot device from UEFI to the NVMe drive (basically stopped using UEFI boot) Cheers, Matti
