[Bug 280202] Re: [intrepid] HP Compaq 6715s very slow - need to be blacklisted?

[Fabio Pedretti]

** Description changed:

- In 2.6.27-rc9 I noticed a fix/blacklist (commit e84956f92a846246b09b34f2a728329c386d250f) for two ATI laptop that set thermal
- trip points to insanely low values.
- I am using current Ubuntu LiveCD which ships kernel 2.6.27-6.9 and I noticed a similar problem on my HP Compaq 6715s (with latest BIOS F.0D 08/20/2008).

+ Unfortunately this fix does not cover 6715s.

  Steps to reproduce: run current LiveCD (downloaded from
  http://cdimage.ubuntu.com/daily-live/). The system is really slow, the
  fan is always active, but ouput fresh air.
  
  If can be useful, running the following command as found here:
  http://marc.info/?l=linux-acpi&m=121396447214047&w=4
  I get:
  $ cat /proc/acpi/thermal_zone/TZ*/trip_points
  critical (S5):           105 C
  passive:                 16 C: tc1=1 tc2=2 tsp=100 devices=C000 C001 
  active[0]:               16 C: devices=C39B 
  active[1]:               16 C: devices=C39C 
  active[2]:               16 C: devices=C39D 
  active[3]:               16 C: devices=C39E 
  
- Maybe it should blacklisted also this hardware?

- Apparently the patch is available at
