--- Comment #29 from Alexandre Demers alexandre.f.demers@gmail.com --- Just in case, I went back in time for bisection between v3.11 and v3.10, began at commit 69e0b57a91adca2e3eb56ed4db39ab90f3ae1043 when dpm was implemented on Cayman. I applied patches from bug 68235 so I could run without display hanging. I've been running videos, daily tasks and piglit runs without a crash. I'll move forward and see if I can find something that could help us explain the hangs happening since v3.11.0.
