ASUS Crosshair Formula V, BIOS 1301 (current) AMD FX-8150 32GB DDR3-1333 RAM Before there the system run with the following components: OSS11.4 MSI K8N2 Diamond FX940 8GB DDR2 RAM After the upgrade I had sporadic system freezes (only Reset helped, no kernel panic!). In the messages.log I found some errors: Apr 15 15:12:16 achim-linux kernel: [ 3900.695217] [Hardware Error]: No human readable MCE decoding support on this CPU type.

Apr 28 17:44:53 achim-linux kernel: [ 300.705150] [Hardware Error]: cache level: L2, tx: DATA, mem-tx: DRD Mostly CPU2 was affected, sometimes CPU3 I have limited the problem so far as possible. If the Vanilla-Kernel was running only error messages (sporadic) come without a system freezes. If the Desktop-Kernel was running, it comes error messages (often) + system freezes. Furthermore the problem occurs only if the power save mode C6 was activated in the BIOS. If I activate only C1E then there comes no errors.
