Comment 6 for bug 1864930

I booted into minimal non-GUI ubuntu20.04 1.4G with 5.4.22-050422 kernel

I removed all possible kernel modules by repeating few times next two commands:
lsmod | grep 0$ | sed 's/^\([^ ]*\).*/rmmod \1/g' > rmmods.sh
source rmmods.sh

root@kubuntu2004:/home/marian# cat /mnt/ub2004min/root/lsmod_fail_s2disk_5.4.22-050422-generic.txt
