I have tested this patch out a fair amount, and it seemed to make things much more reliable, but I have managed to lock up the port again this afternoon. Below is some tracing showing ata4 being frozen and not thawed: __ata_port_freeze: ata4 port frozen ata4: hard resetting link sata_link_hardreset: ENTER ata4: COMRESET failed (errno=-32) sata_link_hardreset: EXIT, rc=-32 ata4: reset failed (errno=-32), retrying in 33 secs __ata_port_freeze: ata4 port frozen ata4: hard resetting link sata_link_hardreset: ENTER ata4: COMRESET failed (errno=-32) sata_link_hardreset: EXIT, rc=-32 ata4: reset failed, giving up ata_eh_recover: EXIT, rc=-32 ata4.00: disabled ata4: EH complete ata_scsi_error: EXIT The IRQ for that port is masked off afterwards.
