Hello,

I have a new MSI FSR Delta (VIA_KT880) and AMD Sempron 2600+, and now after
loading _processor_ module I do not have CPU temperature in /proc/,
and _thermal_ module is not working.

Question:
1. Is this an ACPI fault that my CPU is not compatible with kernel?

Result from /proc/:
./proc/acpi/processor/CPU1. # v

Now I have "throttling control" with issue "no", so ACPI is an author of that
mistake?

Take care.


P.S. I am using setpci to cool my CPU. Like this:
.~. $ cat /etc/conf.d/local.start | grep -v ^# | grep setpci
setpci -H1 -s 0:0.0 82=$(printf %x $((0x$(setpci -H1 -s 0:0.0 82) | 0x80)))
setpci -H1 -s 0:0.0 85=$(printf %x $((0x$(setpci -H1 -s 0:0.0 85) | 0x02)))
.~. $ 

PP.S. thermal:
./proc/acpi/thermal_zone. $ v
razem 0
dr-xr-xr-x  2 root root 0 sty 12 17:05 .
dr-xr-xr-x  4 root root 0 sty 12 15:57 ..
./proc/acpi/thermal_zone. $
