It is necesssary to first test whether you're running into said kernel
bug, before considering other possibilities. For this, you will need to
set read-ahead to zero, not something small.
hdparm -a0 /dev/hdd
will do it. So might blockdev. Check with hdparm /dev/hdd
Note this will make your DVD drive very slow. It is sufficient to
disable read-ahead from another shell while your reading is going on, as
long as you make sure that you do it well before the kernel reads near
the end of the recording.
