I am still seeing this issue with "3.13.0-24-generic #47-Ubuntu" in the 14.04 release with all updates applied.
Connecting an USB 3 device to my computer's front (USB3) port and reading large files from it will trigger repeated USB bus resets. Please reopen. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1293361 Title: xHCI regression(mass storage devices fail) in stable 3.13.5(14.04) Status in “linux” package in Ubuntu: Fix Released Status in “linux” source package in Trusty: Fix Released Bug description: Mar 11 02:00:25 u-ThinkPad-X240s kernel: [ 299.252465] usb 3-2: reset SuperSpeed USB device number 2 using xhci_hcd Mar 11 02:00:25 u-ThinkPad-X240s kernel: [ 299.268395] xhci_hcd 0000:00:14.0: xHCI xhci_drop_endpoint called with disabled ep ffff880046f75980 Mar 11 02:00:25 u-ThinkPad-X240s kernel: [ 299.268400] xhci_hcd 0000:00:14.0: xHCI xhci_drop_endpoint called with disabled ep ffff880046f759c0 Mar 11 02:00:25 u-ThinkPad-X240s kernel: [ 299.540388] usb 3-2: reset SuperSpeed USB device number 2 using xhci_hcd Mar 11 02:00:25 u-ThinkPad-X240s kernel: [ 299.556687] xhci_hcd 0000:00:14.0: xHCI xhci_drop_endpoint called with disabled ep ffff880046f75980 Mar 11 02:00:25 u-ThinkPad-X240s kernel: [ 299.556693] xhci_hcd 0000:00:14.0: xHCI xhci_drop_endpoint called with disabled ep ffff880046f759c0 Mar 11 02:00:25 u-ThinkPad-X240s kernel: [ 299.557393] sd 3:0:0:0: [sdb] Unhandled error code Mar 11 02:00:25 u-ThinkPad-X240s kernel: [ 299.557399] sd 3:0:0:0: [sdb] Mar 11 02:00:25 u-ThinkPad-X240s kernel: [ 299.557401] Result: hostbyte=DID_ERROR driverbyte=DRIVER_OK Mar 11 02:00:25 u-ThinkPad-X240s kernel: [ 299.557403] sd 3:0:0:0: [sdb] CDB: Mar 11 02:00:25 u-ThinkPad-X240s kernel: [ 299.557405] Read(10): 28 00 00 00 35 a1 00 00 66 00 Mar 11 02:00:25 u-ThinkPad-X240s kernel: [ 299.557415] end_request: I/O error, dev sdb, sector 13729 http://www.spinics.net/lists/linux-usb/msg103757.html should backport: e2ed511400d41e0d136089d5a55ceab57c6a2426 469d417b68958a064c09e7875646c97c6e783dfc To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1293361/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
