I have the same issue. In fact, I've been having this issue for years, probably since I own the hardware.
The issue happens when I turn off my screen and turn it back on, and does so reproducibly. It only affects DisplayPort.
My card is a Cayman, and I'm building the X stack from git.
I've attached the relevant dmesg and the Xorg.0.log directly after the issue appeared.
