Something's up with this bug... SATA uses the SCSI layer, right? It could then perhaps be these bits in tip:out-of-tree: 813104e: Revert "[SCSI] simplify scsi_io_completion()" 84db545: Revert "[SCSI] Fix uninitialized variable error in scsi_io_completion" 0eb6038: Revert "[SCSI] Fix error handling for DIF/DIX" 3cd94dd: Revert "[SCSI] scsi_lib: don't decrement busy counters when inserting commands" c27aed5: Revert "[SCSI] scsi_lib: fix DID_RESET status problems" i needed these to keep an aic7xxx box from crashing. This regression got introduced at around 2.6.28-rc1, so it fits the timeframe. Ingo
