It may simply be that your new kernel _is_ running hotter. There was a discussion about such an issue on the kernel mailing list a few weeks ago. The fix should be in the latest kernel. Maybe it isn't included in the Ubuntu 10.10 release yet. > Just running sensors give me: > > acpitz-virtual-0 > > Adapter: Virtual device > > temp1: +26.8°C (crit = +127.0°C) > > temp2: +61.0°C (crit = +85.0°C) > > Since I've little or no load on the CPU, I find the latter value unlikely high (but it seems to be dropping now so I'll guess I will see how it evolves). Anyway, I ran sensors-detect, and it found next to nothing apparently.

Looking at sensors-detect again, I have this: > I don't think laptop price has any correlation to chip support in the kernel. I'd be happy to add that support for the chip in your laptop if someone provides me with a chip datasheet and donates a laptop. > Probing for Super-I/O at 0x4e/0x4f > > Trying family `National Semiconductor'...

Don't recall seeing this specific ID, though, or why it is identified as National Semiconductor.
