So, I've re-read all the comments above (in particular #8) and the only thing at this moment I can really think of (and that you somehow already hint in your comments) is a BIOS issue. The state of your hardware is left in an unclean state and the device driver isn't able to recover from that. And the wistron_btns device driver pretty much invokes some BIOS code in order to do its job, which further corroborates this theory.
Is there a chance that you're not running the latest BIOS for your hardware? Could you check if there is a BIOS upgrade for you laptop? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/926012 Title: With a -pae kernel, freeze during boot when wistron_btns loaded To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/926012/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
