Hi,

You are my hero Jiri :-) These two patches fixes the issues I was seeing and I can no longer reproduce them.

I have only tried them on one hardware platform yet; the one that I had failing: Atom Intel e6xx CPU with EG20T PCH platform controller. I have had approximately 300 boots in our test rigg now and no fails yet. Before was the failrate 1/25 boots.

I made the kernel based on 3.10.9 stable tag and applied them directly on there. I do recommend that these patches makes it way into the stable tree :-)

Thanks again :)

Best regards
Andreas Lillebø Holm
