Hi Thomas,
Just a bit of extra information. I disabled the ICH8 controller
entirely in the BIOS, and booted with a 6.1-RELEASE kernel. The box
still hangs up with atapicam loaded and I can't read files from a
udf-mounted DVD with or without atapicam.
I'm also copying another user on this since he's having similar
problems with the Asus P5B Deluxe.
Thanks,
Josh

I have tried two different Intel P965 chipset based boards with the same problem (Asus P5B Deluxe, Gigabyte DS3). I have tried 2 other DVD devices and an old 50x CD drive. I've replaced cables, tried the device on the controller by itself, and even tried a 3rd party PCI PATA IDE controller. None of the above fixes the problem.

I was able to mount a CD disc and copy files, but I do get the same error for larger files on a couple of CDs. I am using a custom kernel config, but with only a few additions from GENERIC/SMP. And the same problem occurs with the GENERIC/SMP kernels. If I load atapicam, I see in dmesg:
