I've been getting these messages since about 2.5.45. I can't mount any
cds at all. Elvtune (util-linux-2.11r) also fails on /dev/hda which I'm
running on, and /dev/hdc, my cdrom.
Any further info needed?

This is the right behaviour for a CD

Ditto
- so the hdparm is fine, but the I/O error probably isnt

That was at boot, in the dmesg. Full dmesg is posted already.

Same here. I have disabled DMA for cdrom(CONFIG_IDEDMA_ONLYDISK=y)
and things are working again, perhaps with a loss operformance?
Hope it helps.

Unfortunately it doesnt, I still get the err with DMA disabled on hdc.
