[Andrew Cloke]

Thanks. I've adjusted the bionic verification tags accordingly.

Are you also able to verify the cosmic candidate package referenced in
comment #8, and available from
https://launchpad.net/ubuntu/+source/skiboot/6.1-2ubuntu0.1?

Bug description:
  [Impact]

  - Without the fix, the system will crash on upstream hostboot with NMI enabled systems when opal-prd occ reset is triggered on OpenBMC boxes
  - This patch enables HBRT to use HYP special wakeup register in openBMC which until now was only used in FSP based machines

  [Testcase]

  - opal-prd occ reset

  [Regression Potential]
  - Failure of OCC reset command

  On upstream hostboot with NMI enabled, opal-prd occ reset crashes. The following upstream patch needs to be backported to the package to avoid the error.
