Strange. If you read data from the harddisk on an IDE channel and write it
(with cdrecord) to some CDRW on the same IDE channel, you have to expect
trouble: As with IDE there is no disconnect from the bus (as opposed to
SCSI), you risk buffer underruns.=20
A lockup however is not to be expected :-(
