unless there's indication that some driver is causing the machine checks, there's nothing we can do here.  As the message says, most of the time, these are hardware problems of some kind.

Created attachment 550094 [details]
Overheating MCE warings

Actually, there has been an issue where a process ran that caused the cpu to get really warm but that was solved. The messages in the attachment were given in the messages log.

Could it be possible that there is some information stored somewhere about this error and it needs to be cleared to solve the machine error at start-up?

Like with the IML on HP servers?
Comment 3 Dave Jones 2011-12-30 22:01:26 UTC 
no, machine checks get logged as they occur, so this isn't replaying old events.

as the message states, this is very likely some cooling problem with the hardware, and not something we can fix or work around in software.
