Subject: MCE/Package power limit notification

Hi,

After half an hour of compiling code on an Intel SNB machine, at which time
the machine was more or less permanently running with turbo boost active,
I've gotten the following in my dmesg with Linux-3.1.0:

CPU2: Package power limit notification (total events = 1)
CPU3: Package power limit notification (total events = 1)
CPU1: Package power limit notification (total events = 1)
CPU0: Package power limit notification (total events = 1)
CPU2: Package power limit normal
CPU3: Package power limit normal
CPU1: Package power limit normal
CPU0: Package power limit normal
[Hardware Error]: Machine check events logged
CPU1: Package power limit notification (total events = 655)
CPU2: Package power limit notification (total events = 655)
CPU3: Package power limit notification (total events = 655)
CPU0: Package power limit notification (total events = 655)
CPU3: Package power limit normal
CPU2: Package power limit normal
CPU1: Package power limit normal
CPU0: Package power limit normal
[Hardware Error]: Machine check events logged

Below is the output from mcelog. Is there anything that can be done about it?

Cheers,

	- Udo
