I've updated my BIOS, but it made no difference.

I went through the mainline kernel images on http://kernel.ubuntu.com/~kernel-ppa/mainline/ and installed a couple of them and tested them, with interesting results:

 v3.2-rc7-precise/ Works without 'noapic'
 v3.2.1-precise/ Works without 'noapic'
 v3.2.2-precise/ Requires 'noapic' flag
 v3.2.4-precise/ Requires 'noapic' flag

So the regression must have happened between v3.2.1 and v3.2.2.

How can I further debug this?
I've heard mention of git bisect - is there a good tutorial somewhere that can teach me how to use this to find the bug?

I'm going to look for version history now, see if it can shed some light on what changed.
