Subject: C-States on Inspiron 6000
Date: Mon, 07 Nov 2005 17:57:57 +0000	[thread overview]
Message-ID: <1131386277.16106.19.camel@localhost> (raw)

I'm experiencing problems with ACPI C-States higher than 1 an Inspiron
6000. At any higher setting Xorg graphics are choppy and input from the
touch-pad is not recognized correctly (e.g. button clicks only register
as half-clicks or don't register at all). If I set max_cstate to 1, the
problems disappear, although the CPU is about 6 degrees hotter at rest
than max_cstate=4. At max C-State 1 the CPU is idle, but at higher max
C-States it displays constant spikes.

The problem occurs on both Gentoo 2.6.13 and 2.6.14. This problem is
always reproducible, by simply changing the max_cstate setting from 1 to
2.

(Please CC me replies).

Thanks,

-Si.
