Subject: Switchable-graphics issues on HP Envy17 3D (Intel/Radeon) Mini-DP
 works fine but eDP does not

Hello,

I just got a brand new HP Envy17 3D laptop and I'm trying to debug why
the switchable graphics do not work.

Using 3.2-rc3, the internal eDP and the external Mini-DP both work
fine at boot (using intel KMS and X.org).  Unfortunately, if a use
"vgaswitcheroo" to switch to the Radeon chip, I get link failures on
the internal eDP (although the external Mini-DP link works fine after
the switch).

I've attached a boot log of a switch with "drm.debug=0x04", any advice
or debugging assistance would be much appreciated.

Cheers,
Kyle Moffett
