After installing the Hewlett Packard server monitoring agents, DRBD takes
around 2 minutes to startup/shutdown.  It appears stuck in modprobe/rmmod.
This problem exists on several DRBD cluster with similar hardware
configuration.  DRBD seems to perform as normal after kernel module is loaded.

Has anyone seen this problem?
