I'm waiting for your debug instructions on that one, because we already

I already got that patch in my distribution, and now my machine boots up
uninterrupted. The lock is somewhat random, and will go away as soon as
I press the power button on my machine.

Maybe you didn't update to the latest firmwares on you Mac Mini, and
didn't see the problem with the updated BIOSes, I don't know.
