Commands sent to FW, after chip reset got stuck and never freed as FW\n is not going to respond to them anymore.\n\n2. BUG_ON(cmd->sg_mapped) in qlt_free_cmd(). Commit 26f9ce53817a\n (\"scsi: qla2xxx: Fix missed DMA unmap for aborted commands\")\n attempted to fix this, but introduced another bug under different\n circumstances when two different CPUs were racing to call\n qlt_unmap_sg() at the same time: BUG_ON(!valid_dma_direction(dir)) in\n dma_unmap_sg_attrs().\n\nSo revert \"scsi: qla2xxx: Fix missed DMA unmap for aborted commands\" and\npartially revert \"scsi: qla2xxx: target: Fix offline port handling and\nhost reset handling\" at __qla2x00_abort_all_cmds."
