*** Bug 100940 has been marked as a duplicate of this bug. *** Following the machine wedge in bug 100942, we failed to end up with the hw in an idle state. So this is a consequence of i915_gem_set_wedged() not doing its job correctly - but is a secondary bug, if we fix the GPU reset we might never hit this path again outside of igt/gem_eio. Adding tag into "Whiteboard" field - ReadyForDev The bug still active *Status is correct *Platform is included *Feature is included *Priority and Severity correctly set (In reply to Chris Wilson from comment #2) > Following the machine wedge in bug 100942, we failed to end up with the hw > in an idle state.

The reset wedging the gpu should be now covered: https://bugs.freedesktop.org/show_bug.cgi?id=100942 And as this was the secondary effect of that bug, reloading on wedged gpu, we should not take any action. *** This bug has been marked as a duplicate of bug 100942 *** |
