--- Comment #9 from Borislav Petkov
After following your steps (activating MWAIT, C6, running your script) the tests are running into CPU stucks with the result that the system is totally blocked.
Ok, good, that confirms what I was suspecting.

Right, that's the memory failure thing and not the MCEs I was looking for. Ok, thanks, you can continue running with idle=nomwait for the time being. I'll get back to you. -- You are receiving this mail because: You are on the CC list for the bug.
