2.6.31.1 mainline also exhibits this symptom. 2.6.32 does not exhibit this symptom.

On my hardware, reverting brasero and libbrasero-media0 to 2.27.92-0ubuntu2 indeed "fixes" the symptom regardless whether 2.6.31.1 or 2.6.32 is used.

At this point it's pretty safe to say that there _may_ be some additional error handling needed in drivers/scsi/*, but it's more probable that brasero should be fixed. Normally unaligned transfers are caused by higher layers, which seems to be the case here. Also, no ("pure") Kubuntu users are experiencing this issue, since brasero isn't used.
