good day!
next problem:
keyboard (on Dell Inspiron 3179) not sends KEY-RELEASE events (key-up) for keys:
HOME, END, PGUP, PGDN. (problem only for this four keys of keyboard).
for this four keys -- KEY-PRESS sends, but KEY-RELEASE missed.
some software (all X11 software) can not normally works with this issue.
as I checked -- the problem independent of operating system. and very effect on me (I very use X11 software).
proof of presents problem:
if we will load kernel (linux) with kernel paramenters: i8042.debug i8042.unmask_kbd_data
than we will see in dmesg:

Question!:
is it defect of Laptop Keyboard?
or is it defect of Laptop Firmware (BIOS) ? in this case: will this be fixed in next version of Laptop Firmware (BIOS) update ?
thanks in advance!
