I built and booted 6.1.103-rc3 and didn't hit anything. Does it still
trigger with that one? If yes, how do I reproduce this?

There are no deadline changes since 6.1.102, and the block side is just
some integrity bits, which don't look suspicious. The other part this
could potentially be is the sbitmap changes, but...
