Subject: [FreeBSD] system reports 'invalid bad block table' on boot: why?

Last weekend I've done an experimental install of FreeBSD Gamma (haven't 
got epsilon yet) on ST506 disk based system. During install I answered the
question about automatic bad sector remapping with 'no', the install procedure
subsequently ran bad144. Strangely enough, it didn't make a bad sector table
(well it did make it, but it was empty). When I ran bad144 manually, the
bad sector table was still empty. I added the badsectors that were reported
during the bad144 run by hand, and now the table indeed reflected those
bad blocks.

So far so good (??). When the system is rebooted however, the kernel always
reports something like 'invalid bad sector table'. This makes me suspect that
it will not take bad spots into account, so I/O errors will probably a 
matter of time.

Summary: what is wrong here? 

Wilko (who is happy that he has SCSI disks on his own system ;-)
