Subject: A bug or not? No C states on Turion64 ML-34
Date: Sun, 17 Sep 2006 16:46:45 +0100 [thread overview]
Message-ID: <200609171646.46064.tvrtko@ursulin.net> (raw)
Hi all,
On my new HP Pavilion s7510 PC I seem to be missing C states and CPU power
management capabilities. Frequency scaling works though.
I am not sure if this is even a bug, or an ACPI bug os some sort?
I also tried vanilla 2.6.17.13, or noapic/nolapic but to no avail.
