Maybe you should forward this to linux-r...@vger.kernel.org
It could be some race condition, similar to what happened to me with XFS amd
md10 a few years ako (resolved very quickly btw)

I'd say you have a hardware problem on the backing device. Whenever DRBD
tries to write there local IO fails and then it detaches. So test and
verify that the backing device/storage actually works.
I have ruled a hardware problem out in my case. My raid10 backing device
works perfectly with the kernel module from 9.1.4. The kernel module from
9.1.5 through 9.1.13 fail with:

This appears to be the same problem as in issue #26, or at least related.
Note that this could still be a mdraid bug, however the same raid10 works
perfectly well with the DRBD 9.1.4 kmod.
Also note that the DRBD device starts up OK and resync works as long as both
hosts are secondary. Promoting either host to primary seems to trigger the
error on the host having the raid10 backing device..
