Distribution: Ubuntu 8.10 Hardware Environment: HP Compaq 6715s Problem Description: 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 (2.6.27-rc9 based) and I noticed a similar problem on my HP Compaq 6715s (with latest BIOS F.0D 08/20/2008). 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? Thanks
It would really help things along if you could email a tested patch to Andrew Morton <akpm@linux-foundation.org> "Rafael J. Wysocki" <rjw@sisk.pl> linux-kernel@vger.kernel.org Thanks.
Created attachment 18257 [details] General fix for the issue In fact the attached patch from Andreas Herrmann should fix all of these boxes at once (already in the Ingo's tree).
