When opening a SketchUp model (example) in Firefox or Chromium, after ~5 seconds, the SketchUp logo freezes for ~4 seconds, and we see a blank page. The logs show the GPU hang and browser rendering context failed to initialise.
This has 100% reproducibility on my 12-gen GPU.
On this system with Ubuntu 23.04, I have always seen a GPU hang with the stock Ubuntu kernel or mainline.

- the output of 'dmesg' is at https://quora.org/OJnlVgn4xZ/dmesg.txt
- the output of 'dmesg' with kernel boot args 'drm.debug=0x1e log_buf_len=16M' is at https://quora.org/OJnlVgn4xZ/dmesg-debug.txt
- the output of /sys/class/drm/card0/error is at https://quora.org/OJnlVgn4xZ/i915-error.txt
Since I was able to cause failure uncontained to the rendering process when performing this 5-8 times, there is an argument that this is a security (DoS) issue, though I'll let someone else make a judgement. |
