== Comment: #1 - SACHIN P. SANT <ssant@xxxxxxxxxx> - 2015-06-05 01:28:00 ==
The DLPAR memory operation succeeds and is not affected by this warning.
== Comment: #3 - Nathan D. Fontenot <nfonteno@xxxxxxxxxx> - 2015-06-05 07:11:45 ==
Looking at this issue further, it appears to only happen when adding memory that was previously removed. When adding memory that has not been assigned to the partition yet the warnings are not generated.
Need to look into the memory remove code paths to make sure we are
releasing the memory properly.
== Comment: #4 - Nathan D. Fontenot <nfonteno@xxxxxxxxxx> - 2015-06-05 07:59:17 ==
I will have to verify in the Ubuntu source, but this seems like this is an issue that was solved previously by commit 2bbcb8788311a40714b585fc11b51da6ffa2ab92.
