[Drbd-dev] [bug] drbd 9: Receiver error

[Goldwyn Rodrigues <rgoldwyn@suse.de>]

Hi,

I compiled drbd-9.0 against Opensuse Tumbleweed and installed it [1].
I applied Linux kernel commit f730c848affc05fb7262574b06e0cd7e1fa96096 
to get it to compile against the latest (factory) kernels and should be 
the same for the tumbleweed kernel (3.18.3 based) I am using to test.

I am getting the following receiver errors in the kernel log when I try 
to start the drbd service:
