It slowly got worse until my whole system wouldn't start. Finally I ran
btrfs check --repair /dev/sdx1 from a usb boot drive and it said: "cache
and super generation don't match, space cache will be invalidated"

After that it mounted right away. However I will proceed with the newer
kernel as we don't know what caused the corruption in the first place and
why it didn't resolve this automagically.
