Every once in a while, I still get: [drm] GPU HANG: ecode 6:0:0x85fffff8, in supertuxkart [101085], reason: Hang on rcs0, action: reset drmn0: Resetting chip after gpu hang My drm, when loaded, also does this: Failed to add WC MTRR for [0xe0000000-0xefffffff]: -28; performance may suffer This might only be tangentially related, if at all. But, does anyone else see this when you load i915? -- Kevin Zheng kevinz5000@gmail.com | kevinz@berkeley.edu | PGP: 0xC22E1090
