Following up on my own message:

Jeg har nu fundet frem til "Linux SG FAQ", som omtaler noget, der
kunne være mit problem:

	In the linux 2.4 kernel series there has been an increase in
	problems when the ide-scsi driver is used so that cdrecord can
	control ATAPI (IDE) cd writers.
	
	The problem may be related to the aggressive manner in which
	the IDE subsystem attempts to optimize the speed of transfers
	to devices it controls. Some people experiencing timeouts and
	machine lockups have found that reducing the DMA setting via
	the hdparm command has fixed the problem. If the cd writer is
	connected to /dev/hdd then users have reported success with
	these 2 commands:
	
	    hdparm -d0 -c1 /dev/hdd
	    hdparm -d 1 -X 34 /dev/hdd


Med mindre en bedre forklaring dukker op, vil jeg derfor kategorisere
mine problemer som softwarefejl og acceptere, at jeg kun kan brænde
med 4x. Så håber jeg bare, at problemerne ikke også begynder at dukke
op ved lavere hastigheder. 7-9-13.
