That's my guess too, but it is a bit strange that it happens between two minor versions of the same base kernel. But then Debian and Ubuntu backport stuff to their kernels, so that's probably why. > It only starts here with writing on a previously written > volume. A new volume works fine. I have checked and that happens here too: if I recreated and reload the volume no problems, but on the next reboot and mount the problem reappears. I guess I'll try deleting the last checkpoint to see if that helps, and/or looking at what changes between the -72 and -88 versions of the 4.15.0 kernel if anything seems related (there will be lots of changes I guess though).
