Comment 3 for bug 931877

I tested the latest 3.3-rc3-precise kernel, but the same hanging issue still exists. However it seems to be no longer related to udev, but to swapper and kworker (see attached). 1 message is shown about swapper hanging, and another 5 or 6 are about kworker, all hanging the machine for the exact same as the last kernel, and the "acpi=off" boot argument still 'fixes' the problem and allows for a normal boot, but again not having acpi on a laptop isn't good. I have found other bugs reporting the same "task * blocked for more than 120 seconds", however none of them seem to be related to the boot process and therefore i am unable to find a bug that this might be a duplicate of.
