3.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jerome Glisse <jglisse@redhat.com>
commit 51861d4eebc2ddc25c77084343d060fa79f6e291 upstream.
Those rn50 chip are often connected to console remoting hw and load detection often fails with those. Just don't try to load detect and report connect.
