Same here, and vcd's playing out of the cd drive.

After some further testing, a vcd in the dvd drive will have the same 
problem during booting the kernel(before init).  After killing the 
system and rebooting without the disc, trying to play the disc causes 
messages like this repeatedly.  I tried running "cdcontrol -f /dev/acd1 
eject" and it hung.  I tried "atacontrol reinit ata3" and "atacontrol 
detach ata3" and those hung as well.  It's an sata dvd-rw drive over 
atapi.  Here's the error being reported by the kernel.

acd1: TIMEOUT - READ_BIG retrying (1 retry left)
acd1: TIMEOUT - READ_BIG retrying (0 retries left)
acd1: FAILURE - READ_BIG timed out

Mplayer just triggers the problem.  I imagine if I ran amd I'd have the 
same type of problem, or any program that tried to read from acd1.  
Other than locking up tty's and not being able to shut down, the 
system's still usable, aside from the disc inserted during boot of
