Hi,
When the 2.6.0 inits in my laptop it becomes reaaallyyy noisy.
Why ?
A very strange ( sometimes funny when there is no headake ) thing is
that the lan mini-pci card starts doing noises when it receives packets
xD
Best regards and thanks in advance .
Lorenzo.

What sort of noise? High pitched whine?
I fix it with the following patch.
NeilBrown
Status: ok
Reduce HZ to 100
see if it affects noise..

If it's the fans, it's the BIOS reading CPU temperature of 85 C,
which is not true. It seems a Fn-Z press resets this reading to
sane values. You can look at the temperature reading and fan
state with i8kutils.
Atleast that's what a Dell Latitude C640 that I had did.

Might it be that the hardware reports 85 F instead of 85 C maybe? That's about
(85-32)*0.55 = about 29 C, which may be more realistic when you're just
booting it up. :)

Only if it switches between C and F at runtime. Normal readings when
loaded were 55-65, IIRC.
