The currently under-development Ubuntu 14.04 Trusty Tahr is based on
the 3.13 kernel. You can download a pre-release version at

The currently under-development 3.13 upstream kernel enables DPM by
default (without needing the radeon.dpm=1 boot parameter I mentioned
above) for Radeon HD 4000 through Radeon HD 7000 series graphics
processors but with some specific ASICs being excluded.

Kernel 3.11.0-1.4 (based on the upstream 3.11-rc4 kernel) is now
available in Ubuntu 13.10 Saucy Salamander. Also, kernel 3.11.0-2.5 is
in Saucy-proposed, which is based on the upstream 3.11-rc5 kernel, which
has some bugfixes for the new DPM method.
** Changed in: linux (Ubuntu)
Status:
I've just tested the new kernel, and it seems to work well in the sense
that it keeps my laptop at around 60°C when idle. The problem is that,
even at 60°C, my laptop fan is still very noisy. Is 60°C still too hot?
Is it just a hardware problem?

Julien - poor hardware design is a possibility. Also make sure you have
removed all dust from inside the computer, particulary from the CPU and
GPU fans and heatsinks (if it's a desktop, open the case, if it's a
laptop at the very least run a vacuum cleaner nozzle along the external
air vents).
@madbiologist
Thanks for the advice, I'll try them all. The fact that I live in the
south of France probably doesn't help either (it's around 30°C here
now).
As for the firmware, my card is pretty old: ATI RS880M [Mobility Radeon
HD 4225/4250]. I guess I don't need them, right?

According to Wikipedia and
http://xorg.freedesktop.org/wiki/RadeonFeature/#index5h2 the Mobility
Radeon HD 4225/4250 is a RV620 chip, so you shouldn't need the updated
firmware files.

Unlike the older dynpm method, the new DPM method works with multiple
monitors and there shouldn't be any flickering as the performance level
changes are handled by dedicated hardware rather than the driver.

Proper power management for AMD/ATI Radeon R600 and newer hardware is
finally available in the upstream 3.11 linux kernel. The first release
candidate (3.11-rc1) of the 3.11 kernel is available at
http://kernel.ubuntu.com/~kernel-ppa/mainline/ and instructions on how
to install and uninstall it
The thermal monitoring support mentioned in comment #11 is included in
kernel 2.6.36.

Lucid: Overheating due to no PM for ATI KMS

In addition to the Radeon power management patches included upstream in
kernels 2.6.34 and 2.6.35, users with desktop systems may be interested
in some new thermal monitoring work which has just landed upstream.
This work makes it possible to monitor the internal GPU temperature on
newer Radeon
this bug report should be on high importance instead of medium. it
shortened the h/w lifetime.

I definitely agree with Richard - I'd also rate this bug highly
important, especially with the fact in mind that for ATI cards the
xserver-xorg-video-ati driver is used by default on a fresh installation
(correct me if I am wrong here). Also consider this might perhaps lead
to increasing reports
I have just posted thermal measurements as a comment to bug 488152, of
which this is a duplicate. My measurements and long term experience
suggest that passively cooled cards can and will die under the
prevailing conditions. A medium rating seems to underestimate the
problem a bit. I actually

Sounds good to me. I've marked this bug triaged.
Thanks!

I'm using the latest version of Ubuntu 10.04 and can test on three different
machines, all of which exhibit the problem (two in extreme, one in not critical
ways).
Upstream-testing is currently going on with the 2.6.34-series where some
portions of the PM code have been added which
Ho-hum. It seems apport doesn't like my custom kernel and attaching the
logs of Ubuntu's standard kernel won't help since powermanagement
doesn't work there as it's not implemented yet...

Klaus,
thanks for the detail. The issue with apport you have mentioned is one that
i am hoping to discuss and work to resolve at UDS.
Thanks!

You received this bug notification because you are a
one other thing. Would you mind setting an upstream bug watch for the
upstream bug that this is being worked on? Either that or just put a
link in here to it and I will add it.
Thanks!

Jeremy,
There's no upstream bug as this is not exactly a bug per definition, it's more
like a new feature that's being worked on. I don't think it'd be a good idea to
file a bugreport upstream either as this is already under development.
If you want you may consider this bug fixed upstream and
