@Suty Thank you. Sorry I didn't see that thread earlier but yeah that looks like the same issue.
Let me know if there is any logs or other info I can provide. I use NixOS and am happy to try other drivers or settings if there is anything that would be of help.
Something I didn't mention in my report which may be useful toward debugging and fixing this...
Originally the hang would result in my whole machine freezing into an unrecoverable state because the iGPU couldn't reset.
Setting i915.enable_guc=2 means this only resulted in a 30 second freeze like I mentioned in the report rather than needing a complete restart of the laptop.
This may just be peculiar to my system however, not sure but may be useful if you are having trouble working on this issue.
Look forward to the new layers!
