A huge number of ACPI fixes and extensions have gone in since 5.3 was released. That said, 5.4 is getting very close and will have these fixes if you want to wait. You are seeing the temperatures in raw form which is tenths of degrees Kelvin. In Current and 5-Stable these numbers are translated to degrees C. The temperatures you show are not near a shutdown, but the CPU temp can change VERY quickly. 3312 is really very cool. Is your system a P4-M? If so, are you using P4TCC? My experience with P4TCC was that it was not a good idea to play with it as it defaults to automatic. -- R. Kevin Oberman, Network Engineer Energy Sciences Network (ESnet) Ernest O.
