Thermal error while compiling



Hi, I'm trying to emerge packages for my funtoo installation but after a while the system crash due to bad thermal conditions. I suspect it has to do with kernel configuration. I've got an AMD A8 mobile and chose the piledriver stage3. Could someone help me with this?

I've been working quite extensively on the subject lately. First of all here's the output of sensors


# sensors
Adapter: Virtual device
temp1:        +79.0?C  (crit = +100.0?C)
Adapter: PCI adapter
temp1:        +79.0?C  (high = +70.0?C)
                       (crit = +100.0?C, hyst = +99.0?C)
Adapter: PCI adapter
temp1:        +74.0?C  (crit = +120.0?C, hyst = +90.0?C)
Adapter: PCI adapter
temp1:            N/A  (crit = +120.0?C, hyst = +90.0?C)
while acpitool returns the following:

  12. OHC3  S3 *disabled
  13. OHC4  S3 *disabled
  14. XHC0  S3 *enabled   pci:0000:00:10.0
  15. XHC1  S4 *disabled
  16. P2P  S5 *disabled  pci:0000:00:14.4
so if I have understood correctly fan, processor and thermal modules (actually they are built in) have some serious problems.
Is there any chance that BIOS interfere with ACPI? Any other thought?

Decrease the CPU load and frequency will lower the temperature if you can't increase the airflow over the CPU's heat sink.

Post output of this command:

emerge --info | grep MAKEOPTS

This is surely not a problem of air flow: Windows does not show any sort of problem and whenever I use it I never have such behavior. I also opened the case to check whether the fan could be the issue but eventually I didn't find anything about that. It definitely seems that there's something wrong with kernel and ACPI. Fan work but not vigin me any acceptable result: I'm trying to compile libreoffice and have to quit the compilation every 30 minutes to avoid the temperature rise over 80?C. Plus cpufreq seems to work properly...
