Many, many thanks Sergey!!
This problem really fussed me as I thought it's my hardware (as usual).
They must really have fixed a huge bug in 4.4.0.
For the Ubuntu folks here, note that 4.3.4 from Kernel Mainline will still NOT work. (neither does 4.3.0-7, which made it into main repo only 2 days ago, Jan 21)
