Just as an extra data point...

I've compiled the test program an ran it on my ICH7/Pentium D box running
2.6.24-rc1-192-gef49c32 (x86_64), but it does not give the error and
nothing in dmesg. I just get:
result 0

My SATA DVD-RW drive is:
Host: scsi2 Channel: 00 Id: 00 Lun: 00
  Vendor: Optiarc  Model: DVD RW AD-7170S  Rev: 1.00
  Type:   CD-ROM                           ANSI  SCSI revision: 05
