Did you (re)write these files under 2.6.17? Of course if there was a
kernel problem, it could have damaged already existing files too when
you wrote new files.

I am still using Linux 2.6.16.11 but with latest FireWire drivers; their
difference to stock drivers isn't remarkable though. The delta in
drivers/ieee1394 from 2.6.16 to .17 is quite harmless. What may be more
relevant to FireWire behaviour could be changes in the block layer,
memory management, or whatever. I might try 2.6.17 myself RSN...
What type of disk is this bad one? I have two OXFW912 based disks from
different manufacturers, and one of them has always been unreliable WRT
read operations. I noticed only because I use one as the backup of the
other, and when I run a "diff --recursive a/ b/" after having refreshed
the backup, there are occasional differences in a few files. When I diff
these files again, they are suddenly reported to be identical. But I
suppose it is a different problem from yours since I don't get any
access errors besides these silent read errors, and read succeeds on
subsequent attempts. (What slightly worries me is the questionable
service of the backup in a potential restore scenario...)
