GPU lockups are usually caused by a problem with the command buffers generated in the usermode acceleration drivers in mesa. I would suggest trying a newer version of mesa.
How recent should I try? I am already using mesa 10.2.8 and libdrm 2.4.58 . libdrm seems to be a more recent install on 5th Oct, both mesa 10.2.8 was already on when the lock-up happened (twice). mesa 10.3 was released around the same time as 10.2.8 .
Just try a newer or older version and see if it helps. If so, try and bisect to narrow down what change on the mesa side cuased the problem.
