UFS checksum error during arm64 VM installation

Hi, 

We are trying to bring up FreeBSD on ARM64 Hyper-V.  We are seeing the iso image booted up fine and we can install the root disk with ZFS. However, when choosing to install the root disk with UFS, we are seeing UFS checksum errors as below and the installation just failed.

...
UFS /dev/da0p2 (/mnt) cylinder checksum failed: cg 41, cgp: 0x45721f90 != bp: 0x23b0cc8
UFS /dev/da0p2 (/mnt) cylinder checksum failed: cg 42, cgp: 0xbb1ba737 != bp: 0xfc52b46f

UFS /dev/da0p2 (/mnt) cylinder checksum failed: cg 2, cgp: 0x81ae5ff7 != bp: 0xc6e74caf

/mnt: create/symlink failed, no inodes free

We are not sure if this is a UFS on ARM64 problem or Microsoft Hyper-V issue. Any idea?

Thanks,
