[ltp] Temperature problem with my T41p

[Bobby]

I tried cpuspeed but it's the same problem : so I keep it because it =20
loads userspace during the boot, and I add a command line in the /etc/=20=

init.d/cpuspeed for decrease the scaling_max_speed to 1400 Mhz, I =20
think the probe doesn't work very well under GNU/linux because my CPU =20=

is not very hot :/, and no problem under Windows XP. With a max speed =20=

set at 1400 Mhz the temperature increase until 75=B0 : the =20
temperature's shutdown is 94=B0 so it's ok.

For the moment I didn't find a better way for resolve this problem. =20
But in fact my T41p it's not my main machine and I don't need a very =20
high power (except sometimes for rip DVD or this kind of task), so =20
it's not a big deal if my cpu run only at 1400Mhz ;)


Thx a lot for your help.
