Hi James, Im also getting these errors: lpfc 0004:21:01.0: 0:0327 Rsp ring 0 error - command completion for iotag x0 not found lpfc 0004:21:01.0: 0:0713 SCSI layer issued LUN reset (0, 0) Data: x2 x0 x0 lpfc 0004:21:01.0: 0:0317 Rsp ring 0 get: iotag x1700 greater then configured max x1000 wd0 x9032 lpfc 0004:21:01.0: 0:0327 Rsp ring 0 error - command completion for iotag x0 not found lpfc 0004:21:01.0: 0:0317 Rsp ring 0 get: iotag x1800 greater then configured max x1000 wd0 x9032 Which looks a lot like the problem last week which was solved with a firmware update. I'll look into that. In the end the partition locked up with the following backtrace: d000000000078198 .lpfc_sli_validate_iocb_cmd+0x58/0xe0 d000000000079e80 .lpfc_sli_abort_iocb+0xd0/0x230 d000000000092e40 .lpfc_reset_bus_handler+0x210/0x470 c0000000002ee50c .scsi_try_bus_reset+0x7c/0x160 c0000000002ef774 .scsi_error_handler+0x924/0xb20 c000000000014988 .kernel_thread+0x4c/0x6c Anton - : send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
