Whilst I understand your desire to move on and only support 8.3, you
must understand that products using DRBD internally cannot move
instantly to a new release - not only do we have to integrate and
thoroughly test the new release before shipping it to customers, we also
have an installed base that we need to support and fix bugs for.

Obviously it's our problem to do this but some help locating the issues
would be appreciated.

If you could give some hints as to what was fixed that would be helpful.

BTW: it's not even very easy to move to 8.3 internally to see if the
problem has been fixed for a couple of reasons:

1. Changes in the build in 8.3 have made it hard to build from git - I
don't know all the
   details but there are issues with the autoconf stuff when building
from git that cause
   the RPM build to fail.

2. These problems are very hard to reproduce - we need to work hard to
debug from available
   data when they occur because we don't have the luxury of reproducing
easily.
