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?
Cheers,
Zwane
