Perhaps this might help with debugging;
He has CONFIG_BLK_DEV_IDE_TCQ enabled and his IBM supports it,
when he gets to do_rw_disk();
We know its a READ request if (rq_data_dir(rq) == READ) { if (blk_rq_tagged(rq)) return hwif->ide_dma_queued_read(drive);
... the request isn't tagged so we drop down here...
if (drive->using_dma && !hwif->ide_dma_read(drive)) return ide_started;
int __ide_dma_read (ide_drive_t *drive) ... if (HWGROUP(drive)->handler != NULL) BUG();
and ->handler = ?
Is this reproducible? If so without CONFIG_PREEMPT?
