I did some distro hopping with my XPS 15 9575 (BIOS 1.13.0)
Ubuntu 20.04.1 system had the same problem, but I found that the latest Pop!_OS (20.10) and Manjaro (20.2.1) did not have the issue. This leads me to believe that the issue was fixed on systems using updated kernels, such as kernel 5.8.8, but is still present on kernel version 5.8.0-36 that ships with the most up-to-date Ubuntu 20.04.1.
On Ubuntu 20.04.1, I was able to use the workaround found above, by adding "blacklist intel_vbtn" to /etc/modprobe.d/blacklist.conf and rebooting
Will possibly looks into whether Ubuntu 20.10 ships with a kernel that still has this problem
