I have being having identical issues. using standard ubuntu kernels for releases 11.10 and 12.4 . Downloaded and compiled 3.5.4 with same result. Works with usb 2 ports but not usb3.
My tests : 1. use gnome-disk-utility and perform a read benchmark of the drive. USB2 - passes USB3 - Doesn't complete, stops with an error. 2. use md5sum to calculate md5 of the hdd Normally fails at least 1x out of 3 runs with usb3 , no problems with usb2 ports. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1050352 Title: External USB 3.0 hard drive randomly disconnects and connects To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1050352/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
