Hm... damn. My 2.6.36-rc3 with alex' patch didn't give me a freeze for ~ 1 day.
And I'm pretty sure, that I applied the patch correctly and didn't mix up any
of these patches. (did some checks ...)
However, I did a reset of the whole tree, pulled the newest version and applied
alex' patch again.
I'm on 2.6.36-rc3-00185-gd56557a-dirty and testing..
