[LAU] CD ROM Problem

Hope someone can help me on this. I've got 2 LD DVD r/w drives.
Neither one will burn an audio CD for me. When I try it gets to around
track 8 to 10 of 22 and then it craps out. Tried a bunch of different
media and have a nice stack of coasters!

Attempt to create using wodim/cdrecord:

cdrecord dev=/dev/cdrom speed=4 -audio *wav
wodim: No write mode specified.
wodim: Assuming -tao mode.
wodim: Future versions of wodim may have different drive dependent defaults.

The drives in question are (from hdparm):

/dev/cdrom:

ATAPI CD-ROM, with removable media
Model Number: HL-DT-ST DVDRAM GH22NS50
Serial Number: K00998K1011
Firmware Revision: TN02
Transport: Serial, ATA8-AST, SATA 1.0a, SATA II Extensions, SATA Rev
2.5, SATA Rev 2.6
Standards:
Likely used CD-ROM ATAPI-1
Configuration:
DRQ response: 50us.
Packet size: 12 bytes
cache/buffer size = unknown
Capabilities:
LBA, IORDY(can be disabled)
DMA: mdma0 mdma1 mdma2 udma0 udma1 udma2 udma3 udma4 *udma5
Cycle time: min=120ns recommended=120ns
PIO: pio0 pio1 pio2 pio3 pio4
Cycle time: no flow control=120ns IORDY flow control=120ns

And for the other drive:

/dev/cdrom1:

ATAPI CD-ROM, with removable media
Model Number: HL-DT-ST DVDRAM GH24NS50
Serial Number: K00AB5E3326
Firmware Revision: XP02
Transport: Serial, ATA8-AST, SATA 1.0a, SATA II Extensions, SATA Rev
2.5, SATA Rev 2.6
Standards:
Likely used CD-ROM ATAPI-1
Configuration:
DRQ response: 50us.
Packet size: 12 bytes
cache/buffer size = unknown
Capabilities:
LBA, IORDY(can be disabled)
DMA: mdma0 mdma1 mdma2 udma0 udma1 udma2 udma3 udma4 *udma5
Cycle time: min=120ns recommended=120ns
PIO: pio0 pio1 pio2 pio3 pio4
Cycle time: no flow control=120ns IORDY flow control=120ns

And my linux is Ubuntu 11.04, kernel 2.6.38-11-generic-pae

I've checked my cables and all seems to be fine. I don't think it's a
simple hardware thing ... my guess is something to do with irqs. This
is a lightly loaded system. Lots of RAM (7gig) and a dual core AMD
processor.

Suggestions welcome.
