Subject2.4.17-pre2 (and 6) The failed "Read CD" packet command was
Just seen the attached messages while playing a VCD
with xine(0.9.5). I dont know, maybe it's not good to
play vcd, or not good to have a such cd-drive.
Could someone explain?
With linux kernel 2.4.17-pre6 it didn't produce the error
(but the stops while playing are still there). Maybe it's
just xine's problem? After all it has 8-9 threads...
xine output is attached.

vmstat reports unusual high number of context switches
(thread stop - start?)
(>1000 whereas usually 500-600) sometimes. And playback
pauses for ~1 sec. Not especially good.

first vmstat:
