I think this must be related to the Machine Check Exception - I have a similar thing in my log (no tainted modules loaded). Note this relates to cache as well. dmesg: Disabling lock debugging due to kernel taint Machine check events logged mcelog: May 17 03:11:42 zillinger HARDWARE ERROR. This is *NOT* a software problem!
