Thank you for your response.

I see that you have already floated a patch [1] to fix the issue. We will test it and get back to you ASAP.

In case, you still need it.

If you happen to have a device with intel CPU on it (we are seeing it in machines as old as Gen3[2]), you can follow the below steps.

1. Get the latest drm-tip from https://cgit.freedesktop.org/drm-tip/ and install it on the machine

2. Get IGT suite from https://gitlab.freedesktop.org/drm/igt-gpu-tools

3. Build the test suite
    You can use the instructions in the README.md file for building the suite.

    We use ubuntu and I generally do the following

	a) Make sure the packages listed in Dockerfile.build-debian-minimal and Dockerfile.build-debian are installed.
	b) meson build && ninja -C build

4. If everything goes fine, there should be a "build" folder created within the base folder of your repository
    Then run the test using the following command.
	
	sudo build/tests/i915_selftest --run-subtest live

Regards

Chaitanya
