I'm running netbsd-1-5 from cvs update yesterday (1.5.3_ALPHA) on a
new box (1200 MHz Athlon, Asus A7A266 (alimagik1 chipset)).
I am having a similar problem with a cdrom, except that my machine is
not panicing.

The 1.5.2 multi-arch install cd booted, and lost reading the sets.
ftp install went fine.
Then, when running (just fine on two disks on primary ide), the CD
loses (ten-finger copy):

  # dd if=/dev/rcd0d of=/dev/null bs=32k count=20
  pciide0:1:0: lost interrupt
	  type: atapi tc_bcount: 32768 tc_skip: 0
  pciide0:1:0: bus-master DMA error: missing interrupt, status=0x21
  pciide0:1:0: device timeout c_bcount=32768, c_skip=0
  cd0: transfer error, downgrading to PIO mode 4
  cd0(pciide0:1:0): using PIO mode 4
  dd: /dev/rcd0d: Input/output error
  15+0 records in
  15+0 records out
  491520 bytes transferred in 30 secs (16384 bytes/sec)

I tried it again with

cd*	at atapibus? drive ? flags 0x00f0

and reading from the CD usually loses; see info at end of this dmesg.

I booted FreeBSD 4.2 from CD, and went into rescue mode with disk 2.
It also could not read the CD when running FreeBSD, although the BIOS
reads the CD fine to boot from.

Another random question: does the
  Acer Labs M5229 UDMA IDE Controller
shown below handle UDMA mode 5?  The driver seems to set the
capabilities to mode 2 for this chipset, and I can't see why.

I found a few PRs with similar trouble; it seems there is something
subtle going on that hasn't been figured out.

Any suggestions, other than telling me I should have bought an AMD 760
chipset machine with SCSI instead?
