You might want to re-run badblocks on the disk ("badblocks
/dev/sda1" or whatever).  It should print out block numbers that
are troublesome.  (Alternatively, you may be able to calculate
block numbers from the sector numbers given in the log, but I'm
not quite sure how the mapping works.)  Then, you can use "e2fsck
-L" to mark those blocks bad so that the filesystem won't attempt
to use them again.
