Comment 10 for bug 1180649

Is it possible that this bug can affect motherboard efi boot/bios ?
Because when I use windows in my ASUS H97 plus all works fine.

But when I switch to ubuntu, often after an upgrade (signed image) the computer locks itself not booting at all during BIOS UEFI BOOT !!Than I have to remove bios battery and reset bios using jumper (and also pressing boot button for 10 seconds) than after that I regain PC control.

The very first time I had to remove all peripherals from motherboard... This happens only with ubuntu and only after an upgrade... If use ubuntu or Windows normally (no upgrading) I can go on for months without any problems.. BUT if I upgrade ubuntu this not always, but often happens....
