Public bug reported:
Hi, I'm running ubuntu 16.04 (since january) and relatively recently
(after another kernel upgrade during alpha-beta stage) I've started
experience problems with the mouse (it's a radio-powered one). After
checking the syslog that is what I've found:

booting with the "irqpoll" option)
