Hi,
since some time burning ISO CD images as user fails.
Wodim stops during OPC and the kernel prints some messages:
scsi: unknown opcode 0xe9
scsi: unknown opcode 0xed
scsi: unknown opcode 0xf5
scsi: unknown opcode 0xeb
If I burn as root, everything works fine. The used CD writer is a
"PLEXTOR DVDR PX-712A 1.09". I've seen in the wodim/cdrecord
sources that plextor drives are handled different from other drives.
Do you know what the above listed commands are for?
Maybe they could be included in blk_verify_command?
If your'e not sure about the dangerousness maybe as a config option?
Thanks,
Gregor

What drivers and kernel versions work (and which fail)?

The PX-712A still doesn't work right? Maybe it is related to the bug:
http://bugzilla.kernel.org/show_bug.cgi?id=8918
Tejun has the dirve, but nothing new for now.
