Description github 2017-03-31 16:29:49 UTC
This error occoured to me while playing around with Vulkan.

kernel: [drm] GPU HANG: ecode 7:0:0x86f2fdfd, in triangle [30010], reason: Hang on render ring, action: reset
kernel: [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
kernel: [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel
kernel: [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue.
kernel: [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it.
kernel: [drm] GPU crash dump saved to /sys/class/drm/card0/error
kernel: drm/i915: Resetting chip after gpu hang
kernel: drm/i915: Resetting chip after gpu hang

After starting my program (triangle), my Xorg hung for several seconds, then crashed. I saw the above message in my dmesg. Error behaviour differs slightly, sometimes Xorg crashes, most of the time it hangs completely and I have to reboot.

The bug is reproducible under the following conditions:
 - create device memory allocation with size=1MiB
 - create a depth-stencil image with dimensions 800x600 and format VK_FORMAT_D32_SFLOAT_S8_UINT
 - bind the memory allocation (which is obviously too small!) to the DS image
 - draw something and watch it failing

If you really need it, I can attach the crashdump but I would like to avoid this since I'm not sure whether there is some sensitive data inside the render ring dump.

The error code sometimes seems to be 7:0:0x85ffffff, but unfortunately I
haven't been able to get a crashdump for this error code, because the machine
locked up and I had to reboot.

CPU is a Core i5-3210M.

hi, could you please re-check on current vulkan version? If this still actual issue - provide please your application so we could reproduce the issue also.
