 Surely I think the kernel should be fixed as well; however, in this particular
 case, it seems to be intentional panic:
 /mnt: bad dir ino 2 at offset 0: mangled entry
 panic: ufs_dirbad: bad dir
 from ufs_lookup.c:641
 Also, I'm not ufs hacker, so I'm afraid can't fix this part of kernel myself;
 however, I'll be glad to help fixing.
