This is the debdiff with changes from trusty to precise. Those changes are basically fixing behaviour PER comments showing that.

Steps taken to provoke the problem: 1.) deploy any VM instance using nova commands, that is booted from EMC VNX series SAN connected to compute using iscsi, dm-multipath 2.) unplug/disable network connectivity on any of the active paths 3.) check multipath -ll output for faulty failed path/device status. 4.) re-plug/enable network connectivity on the disabled paths 5.) check multipath -ll output for recovering to active enabled path/device status Somtimes the problem occurs when disabling the interface, other times only when re-enabling it.
