Great, thanks for testing!
I've sent the fix to the maintainers of the driver to make sure they
agree with my solution. I'll work on getting the fix into precise once I
hear back.

Great, so far so good.
I've posted a build now with a proposed fix for what I suspect causes
the problem. Please give it a try.

I have a suspicion about this. If I'm right this will be a regression
introduced in 3.2, so an easy first test is to install the 3.1 mainline

Please give that a try and report back the results. Thanks!

It would appear that if the firmware is present, the kernel doesn't

System hangs booting off 32bit live desktop ISO; it has to be power cycled.

Are you trying to perform a fresh Precise install with the non-pae

12.04 is the last release that will support non-PAE. The default (and
