from what I know, ide-scsi is broken in 2.6 and deprecated in favor of atapi burning. You can use cdrecord dev=/dev/hdx. Patches would be much appreciated though.

There is a bug in ide-scsi module (kernel version 2.6.0-test10 with enabled preemptible kernel) - this bug causes SCSI BUS number to be increased by one
everytime ide-scsi module is reloaded (modprobe -r ide-scsi then do modprobe ide-scsi) - it is easy to spot that with cdrecord -scanbus. This bug doesn't appear to exist in 2.4 kernel series, I've not tested this with 2.5 series though, this is not cdrtools fault since I tried both versions (2.00 and 2.00.3) with the same result.When ide-scsi is compiled into the kernel, obviously the SCSI BUS number doesn't increase since there is no possibility to reload it during the same kernel session.
/proc/scsi/scsi says:
Attached devices: Host: scsi13 Channel: 00 Id: 00 Lun: 00 Vendor: LITE-ON Model: LTR-48246S Rev: SS0D Type: CD-ROM ANSI SCSI revision: 02 And here is the reproduction of bug -
1) Before reloading ide-scsi, output of cdrecord -scanbus:

I was trying to fix this bug myself in ide-scsi.c code, but I unfortunately I don't know it's structure...
