[Kernel-packages] [Bug 1535426] Re: CPU runs at high speed after upgrade

2016-01-25 Thread Christopher M. Penalver
Shevek, to see if this is already resolved upstream, could you please
test the latest mainline kernel (4.5-rc1) and advise to the results?

Bug description:
  After a dist-upgrade from 15.04 to 15.10, moving from kernel 3.19.0-43
  to 4.2.0-23, my laptop CPU runs continuously at 3GHz, and never slows
  down to 800MHz, as it used to. This has reduced my battery life from
  24 hours to 8 hours.

2016-01-21 Thread Shevek
Same results in mainline 4.4 kernel. Clock speed almost never drops
below 2.6GHz. I want it to idle at 800MHz when I'm not doing anything
much.

[Kernel-packages] [Bug 1535426] Re: CPU runs at high speed after upgrade

2016-01-20 Thread Shevek
Tried switching to 3.19 kernel - still high speed.
Tried switching to intel X driver instead of modesetting: CPU still runs at 
high speed.

The only changes I haven't backed out are:
a) The Ubuntu 15.10 userland.
b) The BIOS update from 1.07 to 1.10.

With absolutely quiescent system, under modesetting driver, CPU will
settle at 800MHz, but wiggling the mouse or outputting to an xterm
causes the CPU speed to rise. Under intel driver, an apparently
absolutely quiescent system seems to use more CPU than under
modesetting.

powertop is reporting power usage between 12 and 26 W, whereas
previously with 15.04 I had power usage of 5-8W.

Please help, this is killing me. No battery = no computer.

[Kernel-packages] [Bug 1535426] Re: CPU runs at high speed after upgrade

2016-01-20 Thread Shevek
It "feels" as if the system is just too aggressive at ramping up CPU
speed in response to demand? Is this a tuneable parameter? Really, for a
desktop, something should be on a run queue for a couple of dozen ms
before speed ramps up, and with a loadavg of close to zero, that
shouldn't move the needle on this system?

2016-01-20 Thread Shevek
The following things do NOT seem to have any effect:
* Rebooting from cold.
* Suspending and resuming
* Plugging in or removing external power.

BIOS settings are for battery optimized, balanced performance.
Everything is as expected.

The unnamed usb device is the fingerprint reader, which I am not using

not reduce the 8.11W used by thinkpad_acpi, and anyway, i'm somewhat
suspicious of that assignment of power consumption.

[Kernel-packages] [Bug 1535426] Re: CPU runs at high speed after upgrade

2016-01-20 Thread Shevek
More powertop. It's clearly misreporting, and I'm fairly sure the
outstanding power must be going into the CPU, as that's the part of the
system that's physically hot to the touch.

Power est.  Usage   Events/sCategory   Description

Also, this data implies that my backlight has a maximum power of 28
watts, which is false. It's about 5, measured on a nonbroken kernel/bios
/driver-set.

Note, it's not continuously at max speed, it's varying between 2.9GHz
and 3.2GHz. But it never slows down. My load average is very low.

Workaround from that bug: Force low power state:

  CPUs which run at the same hardware frequency: 0
  CPUs which need to have their frequency coordinated by software: 0

  hardware limits: 500 MHz - 3.20 GHz
  available cpufreq governors: performance, powersave
  current policy: frequency should be within 500 MHz and 2.80 GHz.
  The governor "powersave" may decide which speed to use
  within this range.
