The only patch which touches qla1280 is git-block.patch. From a quick
squizz the change looks OK, although it's tricky and something might have
broken.
(the dprintk at line 2929 needs to print remseg, not seg_cnt).
Can you retest with that change reverted (below)? If it's not that then
perhaps something in scsi core broke, dunno.
