Looks like someone found a fairly serious bug affecting some AMD processors. There are two confirmed CPUs with the bug: the Opteron 6168 and Phenom II X4 820. More are probably affected. The bug causes programs or the OS to crash under heavy loads.
I really hope a simple microcode update can fix this.
