The version of powerpc-utils tested was 1.3.4-0ubuntu2.1 from the -proposed repository.

Much testing was done with adding and removing slots. See logs below:

Testing was periodically stalled when I did an strace on pvmutil creating a vterm device (e.g. 'pvmutil -o create_vterm_dev --id 3'). mkvterm calls pvmutil. pvmutil is what uses drmgr. There was confusion when the drmgr logs showed drmgr working properly, however an strace showed writing the slot information to .../add_slot was returning -ENODEV. It was determined that this was not an issue with drmgr, as drmgr was writing the correct slot information.

Therefore, the conclusion is the version of powerpc-utils in -proposed is working as expected.

I am going to open two additional bugs. One for socat, and one for the HVCS and hotplugging issues that will be addressed with kernel commits. Because this bug title only mentions drmgr, we can close this bug.
