Description Anatoly Mashanov 2011-03-19 16:20:01 UTC
Notebook HP Pavilion DV6-3109er (Mobile Phenom II x4, double Mobility 
Radeon) keeps processor temperature about 60 degC under FreeBSD 
8.2-RELEASE GENERIC kernel, and under custom kernel with device 
acpi_video and acpi_hp. The battery life is probably 80 minutes, system 
fan works at low RPM.

The same notebook is only slightly warm under stock Windows 7 Home 
Basic. The battery life there is probably 3 hours. The fan is stopped 
and works only sometimes.

The strange thing appeared: while FreeBSD pciconf reports 2 video cards, 
windows reports only one video card (AMD M880G with ATI Mobility Radeon 
HD 4250, Vendor=1002, device=9712). And Windows does NOT report passive 
equipment, for instance, Ethernet with no cable attached; so Windows 
makes the second video passive and powers it down but FreeBSD does not. 
BTW this second card is still not known to X and to pciconf.

The following was tried, with no or marginal result:
1. Read and followed the Fighting for the power 
2. powerd -v -M 2000 -m 200 (computer becomes non-responsive below 200 MHz)
3. Modification of stock FreeBSD vga driver to recognize one VGA only. 
The second card does not appear in dmesg, hw.pci.do_power_nodriver=3 is in place but temperature is the same 
4. Flashing the freshest available BIOS.
5. Googling everything imaginable about powering down the PCI device - 
nothing found.
6. Looking into book's .ASL
7. Call to HP service.
8. Mailing to freebsd-acpi maillist.

When I rebuild the kernel, the cooling fan properly accelerates and the 
temperature is kept within 75 degC, so the problem is not critical, but 
it's difficult to use the book with battery power.

After a lot of googling and maillist reading I believe that this problem
may be common for all AMD Vision Ultimate platform.

Data files are (If my Apache is OK) 
http://plasmodius.dyndns.org/pavilion - if not, make me know.

How-To-Repeat: Just install 8.2-RELEASE on the said book and look for the temperature.
I believe every book with "ULTIMATE VISION AMD" label is OK.
