Removing irqbalance as described in bug 528720 seems to have got rid of my logon freeze problems.

Have rebooted several times and used it for a few hours without any recurrence yet. -- Mouse & keyboard freeze at logon screen https://bugs.launchpad.net/bugs/586471 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
