            Bug ID: 101491
           Summary: Can't wake up the dedicated graphics card unless power
                    management is disabled
           Product: DRI
           Version: unspecified
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/Radeon
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: drkdfndr@rocketmail.com

dmesg output

I have a ASUS K53TK with a AMD A6-3420M. It has an integrated graphics card the
AMD HD 6520G, and a dedicated one HD 7670M.
I am only able to use the dedicated card if I set the parameter
"radeon.runpm=0".
Otherwise xrandr only sees one provider, and DRI_PRIME=1 can't render any
program.

At boot time, if I don't disable the power management I get several error like
[  458.460874] [drm:r600_ring_test [radeon]] *ERROR* radeon: ring 0 test failed
(scratch(0x8504)=0xFFFFFFFF).

add workaround

PX is known to be broken on K53TK systems.  Add a quirk for another variant.
