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: drkdf...@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).
