[Bug 960925] Re: cpu resources divided to graphic driver

[Atadam]

maybe i have found the troubles source.
according to sensors-detect the only heat management is done by
k10temp
the driver is installed and keeps min temp at 70°C ,which as a result, starts with lower fan speed than necessary to cool.
The altered min temperature does not keep the Laptop really silent but assures that you have a meltdown quicker than intended by trip_points, who start at 46°C.
As a result cooling starts with with a fan speed used for a lower trip point and has to work more often and prolonged.
Since I will restore the driver in any case back to 46°C (if needed with some friends help) i will report my results as soon as possible again here.

with best regards M.Peters

Title:
  cpu resources divided to graphic driver

Status in “acpid” package in Ubuntu:
  New

Bug description:
  Since we had this summer over 45°C and my Laptop did not overheat i was just surprised that after the latest kernel update my Laptop started to do an emergency shutdown now and then. My first try was to change the fan settings in the Bios and oops there is no such thing. Only a choice where you might keep the fan running (I never shut of) or you allow it to shut down if it pleases to do so.  No temperature adjustment. After reading a bit HP site i found that they have a algorithm for fan control and it is obvious that is intended to keep the laptop silent.
  Though silence is not my main trouble but a fresh fried cpu is. 
  Has anybody a idea how to overcome the HP silent treatment and get some adjustment to temperature settings by making the fan work earlier.
  sensors tells me the following but all my feeble attempts to find and adjust it failed so far.

  acpitz-virtual-0
  Adapter: Virtual device
  temp1:       +56.1°C  (crit = +108.0°C)                  
  temp2:       +23.4°C  (crit = +108.0°C)                  

  k10temp-pci-00c3
  Adapter: PCI adapter
  temp1:       +56.1°C  (high = +70.0°C, crit = +100.0°C) 

  I'm good with Horses not with bites (too many teeth).
