Thank you John5788! I have a Asus Z87-Pro and suffered from this problem. After going into the UEFI setup screen and changing the four Asmedia 1074 ports to disabled the system now boots fine.
In the settings screen, they are under Advanced -> USB, and named as USB_ xxE with the suffix E. -- 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
