[Bug 99611] [SNB] GPU hang after over temperature

--- Comment #5 from Chris Tillman <toff.tillman at gmail.com> ---
The initial attachments (already attached to the bug) are all I have. I can
report that the root cause of the overheating was found .. an overheating
internal connector in the power supply chain. The connector was replaced,
and thermal grease re-applied to the heat sink, so the machine no longer
has overheating problems.

The point of this bug was not to trouble shoot my machine; the point was
that the available measurements from coretemp were not being heeded. The
logs show that an overtemperature is reported only for a cycle until it
sets back, saying for example

"[57849.613938] CPU1: Core temperature above threshold, cpu clock throttled
(total events = 12172)"
and then almost immediately (12 microseconds) after,
"[57849.614950] CPU1: Core temperature/speed normal"

It appears from the logs that the only response to monitoring is an
immediate reset of the sensor, and that protection of the machine is not
occurring.
