Comment 0 for bug 1088062

I'm trying to boot into Ubuntu Live CD 12.04.1 (or 12.10 with same result) in UEFI mode on Sony VAIO SVS1311S9RB.
GRUB boots, and if I select any option (try without installing, install or check disk) next thing that i see is message:

    error: couldn't read file.

    Press any key to continue...

after few seconds log with kernel panic pops out:

    Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)
    ...

After this keyboard and touchpad stops working --- I can't enter into BIOS by pressing F2 while booting. They don't work in preinstalled Windows 7 either, Windows reports that keyboard and touchpad device can't be started, error code 10 (drivers reinstallation in Windows doesn't help).
External USB keyboard and mouse works, so computer is not "bricked".

I found that keyboard and touchpad can be "fixed" by randomly repeating theese steps:
 * press power button while laptop is switched off, but do not release it for a 10-30 seconds (hold it even after laptop is shutted down);
 * press "ASSIST" button while laptop is switched off --- VAIO recovery service will boot up;
 * press other special buttons "WEB", "VAIO".
