ide-cd? Can burn DVDs, just not read them...

I just bought a shiny new 16x dvd burner (box says IOMagic IDVD16DD,
drive says Magicspin 1016IM), and can burn dvds perfectly... just not
read them.

Tried with both a dvd I burnt and with a purchased factory-made DVD, on
two computers, with three different IDE controllers, with no change.

Under 2.6.8.1, trying to read files off a dvd instantly oopses. Under
2.6.11.7, reads are very, very slow, pegs the CPU at 100% (with dma
on!), and sometimes give errors in the logs. Under 2.6.12-rc3, reads
don't work at all, 100% cpu, always logs errors, dma gets disabled, and
typically the box takes a reboot to get it usable after trying to read
(box is bogged down; 2 second keyboard delay, etc). Those are using
ide-cd; trying ide-scsi just panics.

Burning works perfectly; 8x burns use about 3% cpu, with no errors.

Motherboard in this system is a MSI 694D Pro (dual pentium 3) with Via
VT82c686a chipset. I use pci=noacpi, as acpi causes other problems
(most notably two of my PCI slots stop working, even with the board
flashed to the latest bios; putting a card in them causes either hangs
or nobody cared errors). Enabling acpi doesn't change the dvd problems.
Tested using both the standard ata/66 controller and the promise
PDC20265 ide RAID controller.

As a test, I drove the drive over to a relative's house, and popped it
into her dual-boot system, with a via 82c596b chipset, no acpi at all.
under 2.6.11.7, it has the exact same symptoms as on my box. Under
windoze, the drive works flawlessly, and can even read the dvds I burnt
under linux with no errors.

I don't have a copy of the oops under 2.6.8.1, however I'm guessing that
has been fixed already, since it doesn't happen under newer kernels.
Under .12-rc3, the following gets logged: (ugly paste alert!)

Errors with "huh?" in them are always fun. :)

In addition, I've attached the complete output of dmesg (at a fresh
boot; attempting to read a dvd very quickly clobbers the boot
information with the errors), in case it's helpful at all.

The errors and symptoms do not change of the DVD is ISO or UDF.

I have also observed problems reading CDs on my cd-rw drive (the other
drive visible in the dmesg output), specifically the log entries, but
without the other problems, and the reads always complete and go normal
speed. Reading a cd gives:

hdg: command error: status=0x51 { DriveReady SeekComplete Error }
hdg: command error: error=0x54 { AbortedCommand LastFailedSense=0x05 }

Any ideas? If there's any tests/output that would help track it down,
I'll be glad to try/post them.

Thanks in advance,
