(and keeps telling so on until reboot).
Maybe it has to do with the initial DMA error. The error itself is another thing, it appeared in about 2.4.21 and also in 2.6 kernels with the new ide drivers. Note that this is normal CD-ROM, not a CD-R nor CD-RW:

And, there is no media in the drive if this matters.
