More useful backtrace at http://david.woodhou.se/cimg2780.jpg
It looks like hwif->rq is NULL when ide_complete_rq() runs. And then it oopses
when looking at rq->cmd_flags.
If I put in a quick hack to avoid calling id_complete_rq() if !drive->hwif->rq,
then it no longer oopses. I get this:
[ 1091.428321] would oops. rq->bio (null)
[ 1091.428323] hdb: request sense failure: status=0x51 { DriveReady
SeekComplete Error }
[ 1091.428329] hdb: request sense failure: error=0x20 { LastFailedSense=0x02 }
[ 1091.428332] hdb: possibly failed opcode: 0xa0
