There is a weakness in the IDE driver in the lk 2.4
series. It tries to autotune for maximum IDE bus
throughput (which means using DMA aggressively).
However if something goes wrong during a DMA transfer
then it is unable to recover gracefully.

You do not need 33, 66, 100 or 133 MB/sec on your IDE
bus to talk to a cdrom, even one that claims to
do "x50". BTW "x1" is about 150 KB/sec.

Yes, try either:
     hdparm -d0 -c1 /dev/hdc
     hdparm -d 1 -X 34 /dev/hdc
