Ok, first off a little "dmesg" action

You can see that I run ide-scsi, an md device (RAID0) and the locations of =
the drives. Now I can *write* a CD just fine, but when I close or "fixate" =
the disc I get IRQ timeouts. Here is a sample from trying to "fixate" using=
cdrecord:

scsi : aborting command due to timeout : pid 2346, scsi0, channel 0, id 0, =
lun 0 Request Sense 00 00 00 10 00

This is the WORST one I have seen so far, it was caused by "cdrecord -v tim=
eout=3D60 -fix dev=3D0,0". I have tried to raise the timeout value to as hi=
gh as 120 with the same results. This CD was successfully "closed" in Win98=
, I was also able to write one all the way through using Windoze. So I know=
this hardware works, and is capable of doing this...
