[xf86-input-evdev] [xorg-x11-7.4] - constantly loses keyboard

[Alon Bar-Lev]

Hello All,

Can someone review [1]

Using evdev for both keyboard and mouse.

Since upgrade to xorg-x11-7.4, the keyboard stops functioning at random
occasions. (xorg-x11-7.3 worked correctly with the same evdev driver).

<Alt><Ctrl>F1 switches back to console, <Alt><Ctrl>F7 switches back to X.
Console works correctly, only X does not accept anything.

Mouse is working.

xev shows no keyboard activity.

No messages in log files. No idea how to debug it.

Bug is opened for long time without any progress.

Any help will be appreciated.

Thanks!
Alon.
