Hi, I'm was running the vanilla Wheezy kernel for my DRBD 8.4.3 tests. If I get to it, I'll try DRBD 8.4.2 again with that kernel. It would still be interesting if this issues is/was already known and "officially" fixed in DRBD 8.4.3 (the release notes don't mention it), as I can't quite test all possible combinations between kernels and DRBD versions.
