A persistent buffer is used and as such the client info is overwritten after the response. During the course of a normal adapter reset the client info is refreshed in the buffer in preparation for sending the adapter info MAD. However, in the special case of LPM where we reenable the CRQ instead of a full CRQ teardown and reset we fail to refresh the client info in the adapter info buffer. As a result, after Live Partition Migration (LPM) we erroneously report the host's info as our own.
