Got it. I suppose that explains why it was so unreliably reproducible.. In any case, the patch is holding strong still with plenty of activity since, so it's looking good. Thak you for all of this; very instructive. On Sat, Jan 06, 2018 at 08:55:00PM +, Chris Wilson wrote: > Quoting

Thanks! It's also a mystery to me why I never had any crashes on any of the other systems running on this machine running the same (unpatched) kernels. I'm assuming the window manager might have something to do with it: all of the others are on i3 and the buggy one's openbox, so perhaps tiling

All right, here's the dmesg from the kernel compiled from drm-tip (in sync with upstream at the time of the compilation earlier today), with CONFIG_DRM_I915_DEBUG_GEM=y I crashed it by opening 20+ xterm windows. Doesn't always do it though (tried this before). On Wed, Jan 03, 2018 at 11:31:31AM

Thank you for that! I'd been getting used to seeing warnings to that effect, so got complacent and stopped checking for errors.. In any case, it's now compiled and installed, and I will report back with any new logs if / when another hang occurs. On Wed, Jan 03, 2018 at 02:53:45PM +, Chris
