Hi, thanks for the bug report. Can you please try in 18.04 with both kernels 4.15 and 5.4? The 4.15 series is the GA series for Ubuntu 18.04, meaning it is the kernel version available since the release of 18.04. Now, through HWE process[0] we get more recent kernels to older releases, so kernel 5.4 is available to Bionic - which is the version on Ubuntu 20.04.
With that experiment, we could narrow it down to a kernel change vs. userspace.

This is undesirable as it also exposes the disks as /dev/sd[abc] as well as /dev/sg[123] No hardware/firmware/bios changes between 18.04 and 20.04.
