I am getting the same errors with most USB 3.0 devices that I tried. These errors come after a ~15 second delay, and this repeats in a loop for 18 minutes. Some other errors may also be thrown, usually related to udev or various timeouts. However, with the USB3 SD reader that I tested, the errors came only once during boot, with only ~15 second total delay, and the boot then proceeded successfully, although the device subsequently did not work. This matches your observations. This all suggests that we are experiencing the same root problem.. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1333229 Title: USB 3.0 regression after upgrading to 3.2.0-64 kernel To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1333229/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
