I have the same problem. I have the Asus Maximus VII Hero (Z97) and the same errors occur. On my PC I have elementary OS 0.3.2 (based on Ubuntu 14.04) installed. While booting with 'normal' bios setting and a USB3.0 HDD my keyboard and mouse (and basically all USB devices) stop working. When disabling the Intel xHCI Mode in the bios there is absolutely no problem. A friend of mine has an Asus Z97-A and he runs Arch and has exactly the same problem.
Update: I flashed my bios to the newest firmware (3003) and with xHCI enabled in the bios my USB3.0 HDD still doesn't work, but all my other devices don't have any problems. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1437492 Title: boot stalls on USB detection errors To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1437492/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
