Comment 29 for bug 1868551

So far no crash, freeze of any kind with Linux 5.5.13 compared to the unstability of Ubuntu 20.04 with Linux 5.4 on Dell XPS 13 with 10th Generation Intel Core i7-10510U CPU (Comet Lake)

I guess the patches are part of Linux v5.5.12 and later
https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.5.12/CHANGES

 Chris Wilson (1):
      drm/i915/execlists: Track active elements during dequeue

 Matt Roper (1):
      drm/i915: Handle all MCR ranges

 Caz Yokoyama (1):
      Revert "drm/i915/tgl: Add extra hdc flush workaround"

Maybe Canonical should backport those patches to 5.4 or switch to 5.5 branch before Ubuntu 20.04 General Availability?
