Hello Jonathan - I'm really sorry about this loooooong delay until getting back to you. Is this problem still valid for you with the latest kernel (preferable from drm-tip)? What kind of user scenario you are/were doing while getting this on dmesg? Did you see any symptoms on GUI when this happened? And please attach full dmesg as attachment while doing the update on this.
Hi Jonathan, When you get a chance to test this on the latest kernel (https://cgit.freedesktop.org/drm-tip), please provide me the entire dmesg log with drm.debug set to 0xe. This will help me look at all the debugs prints and I would be glad to help you fixing this issue. Manasi
