I rebooted the old kernel and recomiled the system again (with no
errors) and got the same result: floating point exception from
fsck_ffs when run without flags.
When given the -b 32 flag, however, it all worked fine on both ffs
partitions. When running fsck -f it also works normally now, i.e.
it checks and reports no errors on both ffs partitions.
Dunno why the error on one machine and not the other. On the first
machine fsck reported the superblock error and offered to correct it,
which is a much better response than a floating point exception ;-)
The only difference I can think of is that the problem machine has
two ffs partitions and the other box has only one.
