It is the same problem as:

http://bugzilla.kernel.org/show_bug.cgi?id=11732

[ also http://marc.info/?l=linux-ide&m=122865770510761&w=2 ]

Hmm... with additional debug data it all starts to make sense now! :)

Borislav, it seems that ide_map_sg() need to check for REQ_TYPE_ATA_PC now that
DMA is allowed for such requests (so it can use sg_init_one() path for them
instead of the usual blk_rq_map_sg() one)?
