XPS 13 9310 Tiger Lake i7 running Ubuntu 20.10 (machine came with Ubuntu 20.04 from the OEM)

Update to intel-microcode 3.20201110.0ubuntu0.20.10.1 on reboot causes what looks like a black screen with corrupted artifacts on it and the system restarts, from dmesg upon booting into fallback kernel I these errors from previous boot

Kernel with this issue is linux-image-5.8.0-28-generic, falling back to 5.8.0-26-generic in GRUB results in the machine booting up fine

I've tried rebooting several times with the machine on and off power supply and get the same result each time
