What does this mean? Are you reporting this issue against four separate
trees?

This isn't really a useful report to send to kernel mailing lists. This
is a mixture of output from the HMC (Hardware Management Console) and
output from drmgr, a powerpc-specific utility that the HMC invokes
remotely on the host. There's no indication of a kernel problem.
This is just a guess, but please ensure your powerpc-utils package
(which contains drmgr) is reasonably recent. Versions up until something
like 3-4 years ago don't understand the ibm,drc-info properties in the
device tree and may experience failures like this.
If that doesn't help, there is likely some other issue (kernel or not)
to investigate here. Your best route to a resolution is probably to file
an internal bug and make the test environment available to a developer
who can look into it.
