Dear Kernel Folks,
I am trying to determine the cause of the poor performance of a
an IDE DVD device on my new machine. I have an IDE Panasonic DF-210-type
DVD-RAM/R/ROM in a new machine with Soyo KT333 motherboard. It
transfers data slowly (below DVD speed), consumes large amounts of
system time, and slows down the user interface and even system
clock (which can run as slow as 1/4 speed while the drive is
going).
The interrupt ERR count below seems to be mostly related to use
of the DVD drive.
Maybe it's something simple. If not, I'll be glad to do further
work to help diagnose the problem.
Here are some possibly relevant details:

Have you tried enabling DMA on the drive?
