Hi @marc, well it was booting something like a month ago. I cannot however tell exactly which kernel version I was using (I think it was already 5.11 lineup, but I am not sure).
Hi @pkondrat I’ve changed by kernel parameters to enforce cgroups v1 (cgroups - ArchWiki). Problem was that it only worked for the LTS kernel (5.10 lineup), not zen kernel (stuck on boot). Do not know exactly why, however the suggested workaround helped. Thank you!
