Well I can reliably make it stop locking the system completely now. I switch to console with ctrl+alt+f2 as soon as the game locks up and then back as soon as the ring stall messages start to fill up the screen. When I am back the game is not frozen anymore, but extremely slow. In fact all opengl related rendering becomes slow. And I get this message each time I switch to console : "GPU fault detected 146 0x0904xxxc VM_CONTEXT1_PROTECTION_FAULT_ADDR 0x00029E48 VM_CONTEXT1_PROTECTION_FAULT_STATUS 0x040xxxxC"
How should I give more information?
If I restart the performance comes back to normal
I think is a similar effect of when DPM is disabled (with 'radeon.dpm=0'). I'm interested to know if DPM has a finger on this issue or not.
Here's a "git diff" between si_dpm.c from kernel 3.16 and 4.7.2: http://pastebin.com/raw/UzZFfYgp
Perhaps there are some hints in there.
