linux bug and lost rows

A long time ago I wrote to the list about a problem I was having with
COPY losing rows from an import file: the number of imported rows was
not equal to the number of rows in the file, and two consecutive imports
from the same file would get different row counts. Several people tried
to reproduce it unsuccessfully. Reference:

More recently, as I was practicing a database upgrade to 8.2.3, I
captured an "unexpected data beyond EOF" in the log, which led to
missing tables in the upgraded db. I opened a thread, and it turned out
someone had previously had the same problem, and it was due to the Linux
kernel version: 2.6.5-7.244
Reference: http://archives.postgresql.org/pgsql-general/2007-03/msg01543.php

Now my server has been upgraded to 2.6.5-7.282, and I'm happy to report
that BOTH problems have disappeared. The first problem, that of lost
rows for COPY, tended to present itself for large import files, nearing
1GB, but I was never able to get reproducible results. As I understand,
the Linux bug responsible for the "unexpected data beyond EOF" had to do
with faulty disk reads. Probably this was also affecting the COPY
command, only failing silently?
