Hello
Since i already had the kernel compiled and ready to boot when i read this, i gave it a go anyway :-).
I can reproduce the freeze with those 4 patches applied, so i can confirm that its, at least, related to, or exposed by, those patches. There must be something else too, or its just too much fuzziness, but the freeze takes a bit more time (approximately five minutes, give or take) compared to the instant freeze before, but its there with the patches, and without them, no freeze.
I assume there isnt a "safe" way to get them out of current .31-rc's, right?
Thank you very much for your time, Joao Correia
