<pre>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.</pre>
