Please upgrade the kernel for Ubuntu 18.04 and 20.04 to fix kernel regression bug!

Hi

There is a regression issue in kernel 5.4.0 relating to the i915 driver. The GPU hangs when doing hardware rendering or video decoding/encoding which we make plenty use of.

See the related launchpad issue:
system hang: i915 Resetting rcs0 for hang on rcs0

In general, isn't there an alternative to patching the kernel in order to obtain GPIO etc? Wouldn't a module suffice? I'm asking as a layman in all things kernel.
