[lm-sensors] ipmisensors problem report on Intel STL2 MB

Hi!

I've tried your ipmisensors patch ipmisensors-20060805-0622.diff on
linux-2.6.17.12, with less success that could be hoped for :(

This is an Intel STL2 dual-P3 motherboard. I'm happy to provide any
other info if interested.

Sensors-detect might be a bit old as it recommends bmcsensors. I
assume that's not a problem, though.

As a sidenote, module unmount crashes things:

2ct2:~# rmmod ipmisensors
Segmentation fault

with dmesg:
