"drbd 8.9.10" is the *utils* version
(drbdadm, drbdsetup, drbdmeta, various scripts ...)

drbd utils version is meanwhile at 9.5.0, btw.  And no, that has not
much to do with what DRBD kernel module driver version you are using,
since we ship the "unified utils" for both "drbd 8" and "drbd 9",
which started years ago already, the utils version is decoupled from
the module versions.

What kernel version,
and what DRBD module version?

Maybe you want to make sure you use the latest 8.4 version (8.4.11
currently), and not whatever "shipts with the debian kernel"?

Well, what does the other node say?
Hit some timeouts?
Some strangeness with the new NIC drivers?
A bug in the "shipped with the debian kernel" DRBD version?
