Can you please attach full dmesg from boot up to the first WARN with drm.debug=0xe? This really shouldn't happen and indicates a bug somewhere ...
A bit difficult ... I originally thought that it was reliably reproducible, but now I didn't get it after 10 suspend/resume cycles. Will keep following it, and once it appears, will send you the dmesg.
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 have this:
[357128.184113] [drm] HPD interrupt storm detected on connector DP-3: switching from hotplug detection to polling
It appeared in the log approximately 5 seconds after resume has been completed.
:( You seem to get this on different connector.
Any chance for a 'lspci -n' output?
Cheers, Egbert.
