Problem:
When using my laptop it suddenly freezes. Nothing works, neither can I switch to stty using CTRL+ALT+F"num" . Nor Can I close any program. If audio is playing, It just loops over that audio creating annoying noise. This freezing happens randomly sometimes when I am using chrome or using emacs (gui) or any other applications. It evens happens with no applications opened. It happened once immediately after the login.

Then I searched the problem above i.e
[drm] ERROR rcs0 reset request timed out: {request: 00000001, RESET_CTL: 00000001}
[drm] GPU HANG: ecode 9:1:85dffffa, in Renderer [20786]
I could not find any definite solution to the problem. Some forums told to change the kernel. I did so but nothing worked out.
I changed kernel parameters as told in
https://johnlewis.ie/tentative-fixwork-around-for-i915-gpu-hangs/
But nothing worked.
Other solution was patching a kernel, But I don’t have any experience building a kernel.
