Very slow CD audio rip with DVD DUAL 4XMax

[Alex Bennee]

Hi,

I was trying to rip some of my collection this evening when I noticed
grip was running at something like 0.3x speed. Investigating the kernel
log I was seeing a whole load of:

ATAPI device hdc:
  Error: Not ready -- (Sense key=0x02)
  Incompatible medium installed -- (asc=0x30, ascq=0x00)
  The failed "Read Subchannel" packet command was:
  "42 02 40 01 00 00 00 00 10 00 00 00 00 00 00 00 "

Messages, followed by the ide subsystem timing out:

hdc: DMA timeout retry
hdc: timeout waiting for DMA
hdc: status timeout: status=0xff { Busy }
ide: failed opcode was: unknown
hdc: drive not ready for command
hdc: ATAPI reset complete
hdc: DMA timeout retry
hdc: timeout waiting for DMA
hdc: status timeout: status=0xff { Busy }
ide: failed opcode was: unknown
hdc: drive not ready for command
hdc: ATAPI reset complete

hdc: status timeout: status=0xff { Busy }

hdc: status timeout: status=0xff { Busy }

hdc: drive not ready for command
hdc: ATAPI reset complete
Losing some ticks... checking if CPU frequency changed.

The drive is a 40x MSI DVD/RW drive so it should be running a lot faster
than that. Any idea how I can figure out what is going on? I've attached
the relevant dmesg dumps:

What else would be useful to figure out whats going on?
