>Description:

	I've been using this machine for long time now and all seems
	to work fine, but today I wanted to listen to a cdrom via
	digital transfer mode in cdplay(4) and this has shown some
	errors:

cd0(jmide1:0:1):  Check Condition on CDB: 0x28 00 00 00 00 00 00 00 01 00
SENSE KEY:  Illegal Request
ASC/ASCQ:  Illegal Mode For This Track

cd0: dos partition I/O error
jmide1:0:1: lost interrupt
type: atapi tc_bcount: 11760 tc_skip: 0
jmide1:0:1: bus-master DMA error: missing interrupt, status=0x41
jmide1:0:1: device timeout, c_bcount=11760, c_skip=0
cd0: transfer error, downgrading to Ultra-DMA mode 3
cd0(jmide1:0:1): using PIO mode 4, Ultra-DMA mode 3 (using DMA)
jmide1:0:1: lost interrupt
type: atapi tc_bcount: 11760 tc_skip: 0
jmide1:0:1: bus-master DMA error: missing interrupt, status=0x41
jmide1:0:1: device timeout, c_bcount=11760, c_skip=0
cd0: transfer error, downgrading to Ultra-DMA mode 2
cd0(jmide1:0:1): using PIO mode 4, Ultra-DMA mode 2 (Ultra/33) (using DMA)
jmide1:0:1: lost interrupt

jmide1:0:1: bus-master DMA error: missing interrupt, status=0x41
jmide1:0:1: device timeout, c_bcount=11760, c_skip=0
cd0: transfer error, downgrading to Ultra-DMA mode 1

jmide1:0:1: device timeout, c_bcount=11760, c_skip=0
jmide1:0:1: piomode timed out

	And so on... any time I use digital transfer mode and play the
	cdrom there's a lost interrupt.
