PM for USB 3.0 hubs isn't supported yet, as they use a completely different protocol for device suspend than USB 2.0 hubs. I'm not surprised the second USB 3.0 hard drive was lost. I'm going to try to work in USB 3.0 hub power management as bug fixes to 2.6.39, but I wanted the main bulk of the USB 3.0 hub support to go in now, since it was such a big API change. > After the first-time hibernate/resume, 2nd USB3 Disk was lost, and there were quite a bits > of error messages. > > Mar 18 04:59:41 ibm-x3550m3-03 kernel: xhci_hcd 0000:1a:00.0: WARN: short transfer on control ep > Mar 18 04:59:41 ibm-x3550m3-03 kernel: xhci_hcd 0000:1a:00.0: xHCI xhci_drop_endpoint called with disabled ep ffff88026c9c6f00 > Mar 18 04:59:41 ibm-x3550m3-03 kernel: xhci_hcd 0000:1a:00.0: xHCI xhci_drop_endpoint called with disabled ep ffff88026c9c6ec0 > Mar 18 04:59:47 ibm-x3550m3-03 kernel: sd 7:0:0:0: [sdd] Unhandled error code > Mar 18 04:59:47 ibm-x3550m3-03 kernel: sd 7:0:0:0: [sdd] Result: hostbyte=DID_ERROR driverbyte=DRIVER_OK > Mar 18 04:59:47 ibm-x3550m3-03 kernel: sd 7:0:0:0: [sdd] CDB: Read(10): 28 00 00 00 00 01 00 00 01 00 > Mar 18 04:59:47 ibm-x3550m3-03 kernel: end_request: I/O error, dev sdd, sector 8 > Mar 18 04:59:47 ibm-x3550m3-03 kernel: Buffer I/O error on device sdd, logical block 1 > Mar 18 04:59:47 ibm-x3550m3-03 kernel: sd 7:0:0:0: [sdd] Unhandled error code > Mar 18 04:59:47 ibm-x3550m3-03 kernel: sd 7:0:0:0: [sdd] Result: hostbyte=DID_ERROR driverbyte=DRIVER_OK > Mar 18 04:59:47 ibm-x3550m3-03 kernel: sd 7:0:0:0: [sdd] CDB: Read(10): 28 00 00 00 00 01 00 00 01 00 > Mar 18 04:59:47 ibm-x3550m3-03 kernel: end_request: I/O error, dev sdd, sector 8 > Mar 18 04:59:47 ibm-x3550m3-03 kernel: Buffer I/O error on device sdd, logical block 1 > Mar 18 04:59:47 ibm-x3550m3-03 kernel: sd 7:0:0:0: [sdd] Unhandled error code > Mar 18 04:59:47 ibm-x3550m3-03 kernel: sd 7:0:0:0: [sdd] Result: hostbyte=DID_ERROR driverbyte=DRIVER_OK > Mar 18 04:59:47 ibm-x3550m3-03 kernel: sd 7:0:0:0: [sdd] CDB: Read(10): 28 00 2b aa 14 74 00 00 01 00 > Mar 18 04:59:47 ibm-x3550m3-03 kernel: end_request: I/O error, dev sdd, sector 5860533152 > Mar 18 04:59:47 ibm-x3550m3-03 kernel: Buffer I/O error on device sdd, logical block 732566644 > Mar 18 04:59:47 ibm-x3550m3-03 kernel: sd 7:0:0:0: [sdd] Unhandled error code > Mar 18 04:59:47 ibm-x3550m3-03 kernel: sd 7:0:0:0: [sdd] Result: hostbyte=DID_ERROR driverbyte=DRIVER_OK > Mar 18 04:59:47 ibm-x3550m3-03 kernel: sd 7:0:0:0: [sdd] CDB: Read(10): 28 00 2b aa 14 74 00 00 01 00 > Mar 18 04:59:47 ibm-x3550m3-03 kernel: end_request: I/O error, dev sdd, sector 5860533152 > Mar 18 04:59:47 ibm-x3550m3-03 kernel: Buffer I/O error on device sdd, logical block 732566644 Sarah Sharp -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
