On this machine I'm running a rc6 kernel + the fix for the accounting bug(¹) that went into mainline ~40 hours ago + the "riskier" patch Mel posted in https://lkml.org/lkml/2012/11/12/151 Up to now everything works fine.

This machine is now also behaving fine with above mentioned rc6 kernel + the two patches. It seems the accounting bug was the root cause for the problems this machine showed.
