Subject[TRACE] 2.4.13 DVD process stuck in uninterruptible sleep
Hi,

(My system is a dual 733 PIII with 1.2 GB RAM, devfs. The DVD ROM is
an IDE drive on /dev/hdc, and the ide-cd support is a module.)

Every now and again, my DVD player process (xine) gets stuck in an
uninterruptible sleep state when trying to access the DVD. This time,
I've managed to produce a couple of traces. This first trace is from
before I Ctrl-Alt-Bkspaced my X session:
