The issues get worse with the Kernel 4.0-rc1-3
versions.
Both Radeon HD6750 and HD7750 oops if HDMI is active but
boot with dvi .
I had tried a bisect on 4.0.0-rc1 but could not get it
finished.
Kernel wont compile after 10th bisect

Proper firmware now included and loading ok.
hda audio driver is loaded and the various outputs

but still no audio out. Can confirm that audio does work
with a Radeon HD6670.
Still same error with the Radeon HD7750

Make sure you've included the proper firmware images. Note the case.
We switched to a new firmware format for SI and newer and the firmware
files names are now lower case (new verde_pfp.bin vs old
VERDE_pfp.bin). The older asics still use the old firmware format
with the upper case names.
As to the audio, I've never tested it on non-x86. Make sure the hda
audio driver is loaded correctly.
