! Did the partition ever have logging turned on?

No, after turning it off, I had run newfs on the partition just to be
sure.

!
! Can you debug or add some code to the  src/vfsck/setup.c
!
!   if (memcmp((char *)&sblock, (char *)&altsblock, (int)sblock.fs_sbsize)) {
!
! to dump these two block to see where the difference is. It was speculated
! that the problem was with logging, but there might be some other error.
! I could send you some code later today.


Yes, I'd be glad to.

Thanks for your prompt response and help on this matter.
