I have experienced some problems with this card/driver. Although it's not
yet in the kernel, I thought I would discuss the problems here and hope we
can work together to find a solution. (It gets a little lengthy here..)
Using the dc395-127 patch with 2.4.0-test2, I get this:

Needless to say, it didn't work too well. I haven't tried any other
recent dev kernels.
Then on 2.2.16:

So far so good, but...
Using a Pioneer 40x CD-ROM (DR-966), kernel 2.2.16 goes up to a load of 2.0.
The system becomes 0% idle. And that's simply installing some games from the
CDROM to an IDE harddrive. However, I have had no problems reading/writing
to/from the MO drive (which is probably much slower than the CDROM).
This is pretty much described in the README. It's here just incase.
Other hardware: athlon, asus k7v, ibm hd.
I would be interested in any ideas. I hope to take a look at it within
the next couple of weeks. Thanks.
