Erros with power_saving and deadlock on Dell R720

[landif]

Greetings to the community Proxmox!


I have used pve since version 2.3. I recently got three new Dell r720 servers. After installing Proxmox 3.1 the servers constantly accuse kernel crashes due to power management performed by APCI 4. After some searching I found that this error has already been resolved to 3.5 kernels as described in:
https://bugzilla.kernel.org/show_bug.cgi?id=42981


Any suggestions?
