Hi Chris, meanwhile my current kernel is 3.16.1-46.1.g90bc0f1 I'm wondering (after a reinstall) that the semaphore bug hasn't occured yet, which was the case before (after a fresh install).
This leads me to 4 definable possible reasons: 1. the named kernel revision somehow contains a fix for it. looking at the changes I could'nt get an affirmation to that assumption. 2. cgroup_memory=disabled has a relation to it. (That's why I removed it for now). 3. the BIOS settings (which could be different now) might have something to do with it. 4. I haven't installed KVM suppport yet. I'll post again if I find a reproducible explanation.
