hi, there
thx in advance;
I encounter a strange (maybe) bug: During the suspending of my linux box(which runs debian 9), I hit the key of the USB interfaced keyboard; after making sure the box enter suspend state for a while ( which I can tell from the power LED blinks), I can NOT wakeup it by hit that keyboard any more. But if I do NOT hit the key during the suspending, I CAN wake it up by hitting the keyboard.
After that I tried Ubuntu 16.04(runs 4.4 version kernel ) and Ubuntu 14.04 ( 3.13 kernel). And I found all of them got the same problem;
Do not know if this is the right place to ask. Just a try.
Sounds like your system does not support USB wakeup, which is very common, sorry. good luck! greg k-h
