3.8-stable review patch. If anyone has any objections, please let me know. ------------------ From: Stéphane Marchesin <marcheu@xxxxxxxxxxxx> commit 0920a48719f1ceefc909387a64f97563848c7854 upstream. This increases GEN6_RC6p_THRESHOLD from 100000 to 150000. For some reason this avoids the gen6_gt_check_fifodbg.isra warnings and associated GPU lockups, which makes my ivy bridge machine stable.
