Comment 36 for bug 1553328

I can still reproduce on mesa 11.0.3 / libdrm 2.4.65 though it takes longer to trigger the bug (a few minutes of usage). This is the backtrace when using these versions of mesa and libdrm, it's somewhat different than the previous one but the bottom frames look the same:
