From: Aristeu Rozanski <[email protected]>
This patch makes the Thermal messages (temperature got past Tmid) to be
displayed only once because:
1) it's the BIOS job to configure and handle the memory throttling
2) if the BIOS is broken or is aware about the condition, flooding the
system logs won't help anything.
3) According to the specification update for Intel 5000 MCHs, all the
revisions of this MCH have problems on the thermal sensors, making
not automatic (a.k.a. intelligent thermal throttling) impossible.
