Yeah, it's working but failing resets are considered highly dangerous (in that the controller status is unknown and may cause something dangerous like screaming interrupts) and port is muted after that. The plan is to handle this with polling hotplug such that libata tries to revive the port if PHY status change is detected by polling. Patches are available but they need other things to resolved to get integrated. I think it'll happen before the summer. Anyways, you can tell libata to retry the port by manually telling it to rescan the port (echo - - - > /sys/class/scsi_host/hostX/scan). > > (H'm... after rebooting, reallocated sectors jumped from 26 to 39. > > Something is up with that drive.) Yeap, seems like a broken drive to me. Thanks. -- tejun
