[Kai-Heng Feng (kaihengfeng)]

Is it a regression? Did it work in older release like 16.04?

[navycat (navycatt)]

No. 16.04.6 have this issue too.

[Kai-Heng Feng (kaihengfeng)]

Can you please test the GA (4.4) kernel on 16.04?

[navycat (navycatt)]

I checked the bug on kernel 4.4.0-21-generic ubuntu 16.04. Bug is present.
