Created attachment 42413 [details] dmesg I get the following message associated with screen freeze every time I do a piglit run : [ 512.205375] [drm] nouveau 0000:01:00.0: PGRAPH - DATA_ERROR INVALID_OBJECT [ 512.205381] [drm] nouveau 0000:01:00.0: PGRAPH - DATA_ERROR [ 512.205387] [drm] nouveau 0000:01:00.0: PGRAPH - ch 128 (0x0002d30000) subc 3 class 0x5039 mthd 0x0184 data 0x00000e02 Previously I got vanishing text/pictures rather than freeze, but this behavior has been there for a long time now. I think it was introduced in October after the 2.6.36-rc7 merge but not 100% sure. This commit makes the problem appear less quickly, but it is still reproducible : drm/nv50: Fix race with PFIFO during PGRAPH context destruction. git as of today: kernel: 64b792 drm: 550fe2 ddx: 38e880 01:00.0 VGA compatible controller: nVidia Corporation G84 [GeForce 8600M GT] (rev a1)
