Title:
  ISST-LTE:Ubuntu15.04: After migration of Ubuntu15.04 lpar, RMC
  connection on HMC will be lost (LPM)(kernel/powerpc-ibm-utils)

Status in linux package in Ubuntu:

Bug description:
  Defect Description:
  ----------------------------

  For Ubuntu15.04 lpar which has Active RMC connection with HMC, once
  the lpar is migrated to another machine in same/different HMC, the RMC
  connection on HMC with the lpar will be lost.

  The following upstream fixes are required to ensure device tree is
  properly updated after migration/suspend and that the RMC connection
  is not lost as a result.
