The error you are seeing:

> [185300.784992] i915 0000:00:02.0: [drm] Resetting chip for stopped heartbeat on rcs0
> [185300.888694] i915 0000:00:02.0: [drm] fgfs[27370] context reset due to GPU hang

That just indicates that the rendering took too long. It could be caused
by a change in how the application renders, userspace driver or i915. So
a previously on-the-edge-of-timeout operation may have got pushed beyond
the timeout, or the rendering genuinely got completely stuck.

If you only updated the kernel, not the application or userspace, could
you bisect the commit that introduced the behavior and report:

https://gitlab.freedesktop.org/drm/intel/-/wikis/How-to-file-i915-bugs

We have changes around this area, so would be helpful if you can bisect
the commit that started the behavior.
