After many kernel builds, new driver installs, I have gotten my scsi cd burner to burn without the dreaded DMA errors.
I had to slow the scsi bus down to 10 MHz....the default is 20. This is done from the commmand line like this: modprobe dc395x_trm dc395x_trm=-2,2,-2,-2,-2,-2 the -2's mean don't change the parametter and the 2 in the 2nd position is the one that changes the speed. I have succesfully burned 2 cd's (audio and data) at 4x which is my usual burning speed although my Plextor will do 12. My next question is: how do I express the above in modules.conf? I tried thse 2: alias scsi_hostadapter dc395x_trm dc395x_trm=-2,2,-2,-2,-2,-2 and also: alias scsi_hostadapter dc395x_trm options dc395x_trm dc395x_trm=-2,2,-2,-2,-2,-2 Neither of these work....the bus is still at 20 on boot and I have to rmmod and then do the above modprobe line. any ideas?
