@John, if you're free, Would you please help to try drm-tip? You cound just download the files with "generic" and linux_header_***_all.deb https://kernel.ubuntu.com/~kernel-ppa/mainline/drm-tip/2020-12-28/
And enable drm.debug=0x11e log_buf_len=16M in grub.
If the issue still exist, please upload the dmesg
