UFS problem?

Hi

Hardware:

CPU: Intel(R) N100 (806.40-MHz K8-class CPU)
  Origin="GenuineIntel"  Id=0xb06e0  Family=0x6  Model=0xbe  Stepping=0

  TSC: P-state invariant, performance statistics
real memory  = 8589934592 (8192 MB)
avail memory = 7981867008 (7612 MB)
….

As harddisk I use a NVME probed as:
nvme0: Allocated 127MB host memory buffer

When trying to install packages I receive:

Mar 26 09:42:03 xxx kernel: UFS /dev/nda0p2 (/) cg 75: bad magic number 0x0 should be 0x90255
Mar 26 09:42:03 xxx kernel: /: bad dir ino 6169868 at offset 0: mangled entry
Mar 26 09:44:18 xxx kernel: /: bad dir ino 6089939 at offset 0: mangled entry

I have tried 13.5-RELEASE and 14.2-RELEASE with the same result.

Somtimes the machine panics.

If I select zfs in the installation process no problems occur even with exactly the same hardware.

If I use a SATA disk everything works.

Please advice
