<pre>I'm using Fedora 24 with kernel 4.7.5-200, GPU Intel Corporation HD Graphics
520 (rev 07). Today I've been forcefully logged out of my X session, and I've
spotted this in the system logs:
oct. 19 19:34:32 mob01772 kernel: [drm] stuck on render ring
oct. 19 19:34:32 mob01772 kernel: [drm] GPU HANG: ecode 9:0:0x85dffffb, in Xorg
[12939], reason: Engine(s) hung, action: reset
oct. 19 19:34:32 mob01772 kernel: [drm] GPU hangs can indicate a bug anywhere
in the entire gfx stack, including userspace.
oct. 19 19:34:32 mob01772 kernel: [drm] Please file a _new_ bug report on
bugs.freedesktop.org against DRI -> DRM/Intel
oct. 19 19:34:32 mob01772 kernel: [drm] drm/i915 developers can then reassign
to the right component if it's not a kernel issue.
oct. 19 19:34:32 mob01772 kernel: [drm] The gpu crash dump is required to
analyze gpu hangs, so please always attach it.
oct. 19 19:34:32 mob01772 kernel: [drm] GPU crash dump saved to
/sys/class/drm/card0/error
oct. 19 19:34:32 mob01772 kernel: drm/i915: Resetting chip after gpu hang
[...]
oct. 19 19:34:34 mob01772 kernel: [drm] RC6 on
oct. 19 19:34:44 mob01772 kernel: [drm] stuck on render ring
oct. 19 19:34:44 mob01772 kernel: [drm] GPU HANG: ecode 9:0:0x85dffffb, in Xorg
[12939], reason: Engine(s) hung, action: reset
oct. 19 19:34:44 mob01772 kernel: drm/i915: Resetting chip after gpu hang
FWIW, this happened right after starting an I/O intensive operation, which
might be related to the hang.</pre>
