dmesg log

Hi,

I have a HP Pavilion dv6-3111sa laptop (circa 2010) with 2 GPUs:

01:05.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc.
[AMD/ATI] RS880M [Mobility Radeon HD 4225/4250] [1002:9712]
02:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc.
[AMD/ATI] Park [Mobility Radeon HD 5430/5450/5470] [1002:68e0] (rev ff)

I am running Ubuntu 16.04.2 with kernel Ubuntu 4.8.0-36.36~16.04.1-generic
4.8.11

The screen usually freezes for a fraction of a second and then again a few
seconds later. It may do this several times. In addition, the computer usua=
lly
locks up before/after graphical login requiring a hard shutdown, although it
doesn't always lock up. It seems to be preventing the computer from shutting
down normally as well.

This appears in dmesg output whenever a freeze occurs:

  186.427140] [drm] enabling PCIE gen 2 link speeds, disable with
radeon.pcie_gen2=3D0

Adding radeon.runpm=3D0 to my boot cmdline solves the issues as a workaroun=
d.

With previous ubuntu/kernel versions, the main issue was the freezing which
would happen every seven seconds with the corresponding dmesg block. This w=
ould
continue ad infinitum, although on rare occasions it would stop after many
freezes. However with my current kernel this pattern doesn't seem to occur =
- it
freezes a few times before the freezing stops and the freezes do not occur =
at
regular intervals.

I'm not sure if this is a graphics or sound issue from the dmesg block. The=
re's
also some ACPI errors in the dmesg log so maybe a firmware problem, or faul=
ty
hardware? I tried some lower level debugging previously but couldn't conclu=
de
anything.

Thanks for any assistance.
