I'm running Linux Mint 15, and my machine is spontaneously rebooting.  It appears to happen when the computer is under load.  Normal use doesn't seem to cause it, but I'm trying to create a windows vm and I can't make it through the install, because the host keeps crashing.  This is what my syslog looks like right before/after a crash.  Can anyone help me decipher this?  FYI Cerebro is the hostname.Dec 21 23:18:33 Cerebro kernel: [    6.294603] [Hardware Error]: MC4 Error (node 0): Protocol error (link, L3, probe filter).Dec 21 23:18:33 Cerebro kernel: [    6.294606] [Hardware Error]: Error Status: System Fatal error.Dec 21 23:18:33 Cerebro kernel: [    6.294608] [Hardware Error]: CPU:0 (15:2:0) MC4_STATUS[Over|UE|MiscV|PCC|-|-|-]: 0xfa000000000b0c0fDec 21 23:18:33 Cerebro kernel: [    6.294610] [Hardware Error]: cache level: L3/GEN, mem/io: GEN, mem-tx: GEN, part-proc: OBS (no timeout)Dec 21 23:23:18 Cerebro kernel: [  301.422760] mce: [Hardware Error]: Machine check events logged
