Feedback on the Dell Latitude 3440 - Latitude OAK 14

After upgrade to 16.04 (from 15.10) suspend/resume doesn't work anymore. The laptop doesn't power down completely on suspend and I have to force power off -- on subsequent restart fsck reports orphaned files on disk. The update also caused a strange problem. Sometimes the system becames almost unresponsive just after power cable or ethernet cable has been disconnected. The culprit is indicator-multiload all of a sudden using 100% of CPU. When I kill indicator-multiload system returns to normal except ethernet carrier is no longer detected.
