Public bug reported: After upgrading ubuntu 14.04 LTS from kernal 3 to kernal 4.4.0-38-generic, we got issues with DRBD. Especially during high load, the drdb kernal will gif issues.
The DRBD status go's to a timeout and the server becomes unstable (also the KVM's running on it) and afther some minutes/hours, the system hangs. Only a hard reset is possible. This problem randomly appear after a few minutes / hours / days. Got this issue on multiple servers. The workaround is to go back to the old kernel.
