(In reply to Edwin KM from comment #20) > Can i go back to a really old kernel? Like a year old? There are unofficial kernel builds for old versions found in my OBS repos, e.g. home:tiwai:kernel:6.6, home:tiwai:kernel:6.5, etc. But 6.6.x kernel still works even after rebuilding initrd without zfs, right? Then the regression is clearly after 6.6.x.
