2.1 is not 'LTS' version, so it's expected that it won't be available
anymore. Personally I'd upgrade to 3.0. But backup /var/lib/lxd (when ALL
containers are stopped) beforehand.

FWIW, I'm more inclined to think your 'kworker' issue might be related to
btrfs instead of lxd, but it might be harder to debug that.
