Can you verify if this is still present? I just did:
$ sudo apt-get install drbd8-utils linux-headers-generic that succeeded in building drbd.ko
Then: $ sudo modprobe drbd
I'm currently booted into -19-generic and have -21-generic installed.
It seems strange that you got the module built but it wont load, rather than failing to build.
