Inspiron 8000 makes high pitch noise only with 2.6.0-test1

Inspiron 8000 makes high pitch noise only with 2.6.0-test1

[Daniel.Dorau]

Hi there,
yesterday I tried the 2.6.0-test1 kernel for the first time.
Installation went flawlessly. However I noticed a high pitch
noise from my notebook everytime after the ethernet driver
was loaded, no matter which one (eepro100 or e100).
It is exactly the noise that my notebook only did with 2.4
when _actually_ transmitting data on IRDA.
I have no clue whatsoever how the same noise is being triggered
by the 2.6 kernel. Disabling IRDA (kernel+BIOS) didn't help.
Since that noise is somewhat nerving, I would be very happy
if someone has an idea how to fix that.
This noise does definitely not appear on 2.4 kernel except when
IRDA is active. On 2.6 I can hear it all the time one the
ethernet driver is loaded. It is only interrupted by heavy disc
activity.
Does anybody has an idea?

Please CC me on reply.

Thank you
Daniel

try turning off 

CONFIG_APM_CPU_IDLE

it help me and others, but it had nothing to do with ethernet drivers...

Joel,
thank you. I will try this. But doesn't this mean, that it will
consume more power? My belief is that this had worked with
2.4 without that noise.
You said it helped you and others. Has this been discussed on
this or some other mailing list?

Thank you
Daniel

Yes, it was discussed at LKML in May (search the archive around May 13).

I think the board idle the processor anyway, my dell latitude does it,
so you don't need linux to do it.
