After Fedora updated the kernel to 4.8 my discrete AMD GPU stopped working. Even the most simple commands like DRI_PRIME=1 glxinfo produce:
radeon: Failed to allocate virtual address for buffer:
radeon:    size      : 65536 bytes
radeon:    alignment : 4096 bytes
radeon:    domains   : 4
radeon:    va        : 0x0000000000800000
radeon: Failed to deallocate virtual address for buffer:
radeon:    size      : 65536 bytes
radeon:    va        : 0x800000
radeonsi: Failed to create a context.
X Error of failed request:  GLXBadContext
  Major opcode of failed request:  154 (GLX)
  Minor opcode of failed request:  6 (X_GLXIsDirect)
  Serial number of failed request:  44
  Current serial number in output stream:  43

Dmesg from booting and attempting to run glxinfo is attached.

I managed to bisect it to:

    Revert "drm/radeon: work around lack of upstream ACPI support for D3cold"
    This reverts commit bdfb76040068d960cb9e226876be8a508d741c4a.
    Now that d3cold is upstream, there is no more need for this workaround.

Reverting this commit from top of the current linux git fixes things for me.
This might be duplicate of bug 98505, however this is with radeon driver instead of the amdgpu, so filling separately.
