Could you check if you get any messages regarding HPD storms after 
suspend/resume ie messages like:
"[drm] HPD interrupt storm detected on connector HDMI-A-1"
but without the annouing warn messages?

I cannot find anything obviously wrong in the code. 
However there are several code paths for different hardware though - could 
you give me an 'lspci -n' output so I can narrow them down?

Thanks!
Cheers,
