Radeon 780M atomic commit warnings at each wakeup from suspend and each monitor vblank
Brief summary of the problem:
After each wake up from suspend OR monitor vbanks I see WARN_ON messages in dmesg. In common all of these is about atomic mode commits. As visible issue - monitor sometimes can't get be turned off by the DPMS when it required.
Also, it sometimes non-longterm freezes in some applications, but in the moment it gets back to the normal. I don't thinks it's related, but just in case, for more information. Probably it is a separate issue.
