which scsi controller is this ? which burner ? can you attach the output of "cat /proc/scsi/scsi" and of dmesg ? Created attachment 100752 [details]
dmesg
Created attachment 100753 [details]
cat /proc/scsi/scsi
Scsi controller is Adaptec 19160 using module aic7xxx. The burner is a Yamaha CRW2100S Try adding -immed to the cdrecord command line options I tried it with the -immed option and it has fixed the problem, I got a slight jump on audio playback at the âfixating...â stage, but no system hangs, which is good enough for me :-) I've done a little bit of reading about IMMED and found that it is used to stop a device using all the bandwidth of the bus it is on. I would understand why this would fix my problem if my hard disk and my cd-writer were on the same bus but they are on 2 separate buses, with 2 separate cables. My hard disk is on the U160 bus, with its own 68pin cable. And My cd-writer is on another bus (don't know which scsi version it is, but it's on its own 50pin cable). Do you have any idea's why this fixes my problem ? Also do you know why this problem has only arisen since the introduction of SG_IO ? This problem has been totally fixed since I upgraded to FC3 (kernel-2.6.9-1.681_FC3), I'm not even getting the slight jump on audio playback anymore. |
