I don't know if it is the same thing, but I have been having lots of issues
lately due to apparmor blocking gnome. I worked around it by disabling
apparmor in the kernel.

One thing I have not seen mention until now, but have noticed is that my

Yes, you got the right idea.
I don't know that it is really dangerous - worst case would be your
driver wouldn't load or lock up, a reboot would fix it.
My scenario works for the iwlagn driver, I don't know if you have the
same hardware.
It does make a 2 - 3 watt difference in power usage for
@Erwin - not sure if you have this same hardware as mine, but I did find
what makes the difference for my laptop.
Natty running 2.6.35 kernel, can idle at 18.5 watts - runs ok, but I
find that power management screws up my primary drive when it goes to
sleep, will not wake up the drive at all,
that is the interesting question.
There isn't really a large discrepancy for the most part.
Phoronix did a piece comparing ubuntu to windows 7, and they actually were
rather close.

that said, there are a few reasons why
well, I woudn't say negativist, but..
I think the power issue is a bit overblown. even in the inital bug report
for this, Natty was like 15 percent more power hungry than the older
versions. And - this is not unique to Natty, or Ubuntu..
if you look around there are bug reports for this exact
I would offer the opinion that this is more like a regression as this
exposed a kernel regression as proper aspm handling requires changes
to the drivers in the kernel.
In the article, it mentions that the windows drivers may have
additional bits for aspm functionality, thus overriding BIOS
Jon- absolutely agree. Only way I can figure this isn't getting more
attention is that the majority of datacenters are using enterprise
versions of the kernel, which are several versions back and aren't
affected yet.
Once RHEL version 7 or 8 comes out with 2.6.38 or later, everyone
would get a
Are you using the stock kernel? Or the patched version further up the
thread?

I did some digging on the lkml forums (hard to add links from the bby)
It looks like all of them relate to a series of commits for the kernel
IPI process. It looks to be added as a way to load balance processes
accross multiple cores in the fair scheduler (CFS) when the kernel is
running
@Alex - is the radeon driver the Xorg driver?
Using the proprietary fglrx one will probably improve things quite a
bit.
Power consumption on the open source stack for both amd and nvidia is
still quite high.
My friend's eepc 1015T dropped about 4-5 watts when I installed the
proprietary driver.
Cjcolla - with over 1000 wakeups per second, I would not think there
is much chance of the processor entering a sleep state at all.
It looks to me like all of the wakeups are from your usb devices, were
you doing much with the mouse or anything like that while taking the
snapshot?

Yes, I noticed.
I compiled up a lucid kernel - 2.6.34, runs fine on natty. Strange
thing I see is that the ACPI reported power usage is the same on my
laptop, about 19 - 21 watts, yet I get 3.5 hours on that kernel
instead of the 2.1 hours on the natty kernel or the 2.6.39 source from
the linus
It might be a cludge, but a workaround might be to disable the
tickless kernel option, multiple core systems and hyperthreading
would still work with a slight increase in overhead- at least until
this has an accepted patch from the kernel folks.

looks like part of this was noticed back in September.

I took the Natty kernel sources and default config and manually applied
the diffs from that thread.
the load balance thread that keeps waking the kernel drops significantly
when idle. - went from 300 or so
built latest kernel 2.6.39-rc5 from latest sources and powertop shows
normal values for power utilization again.
processors show 99 percent C6 mwait residency, full charge battery
estimate is up to 3 hours compared to 50 percent C6 mwait and 1.2 hours
off a full charge
