i've installed the new kernel 4.5 RC1, but i've the same problem.
i've also tried start ubuntu with upstart, same problem.
i don't know why i've this strange problem.

i've also tried GhostBSD on live (i don't know if this information can 
be useful), the problems occurs also on BSD but seem that is less severe 
than on Linux, because on BSD seems that the problem occurs only one 
time every boot, then disappears without do nothing (don't need to press 
MAIUSC key for some seconds).

I hope that this bug can be solved.

Hi, Dmitry
i've the same problem on console without X.
this is an output of evtest on console:
http://pastebin.com/4aWYYhwN
(as you can see, after a while i'm pressing Left_Alt (from line 434 of
pastebin) or Left_Ctrl (from line 605 of pastebin) or Left_Shift (from
line 786 of pastebin), these keys are released and then pressed again.
but when i press only left_shift for some seconds, the issue don't occurs.)

i haven't found nothing on BIOS settings, the only options relative to
keyboard is:

Action Keys Mode:
[Enabled]: Requires pressing only F1 throug F12 to activate action keys
[Disabled]: Requires pressing FN Key + F1 throug F12 to activate action
keys

but the problem occurs in both modes

[1.] i've a problem with keyboard of my notebook HP Pavilion 15
ab062nl; CTRL SHIFT and ALT buttons not works as they should. in
particular, it is as if these keys are pressed and released alone.
isn't an hardware problem, because on windows 10 and windows 8.1 i
haven't these problems, is only a linux problem (all distro).

[2.] the bug is always active, every time i start a linux Distro
(also from live, and also without DE/WM) i've this problem with
keyboard, the only way to fix temporarily the bug, is pressing the
only Left SHIFT key for some seconds, then all problems disappear
indefinitely, and in any case, if i shutdown or if i reboot the PC,
the problem recurs.

Hmm, this is weird. Do you observe the same issue in text console (not
in X)? It would be nice to see events as emitted by the kernel - you can
use evtest utility for that.

Is sounds like some accessibility feature, is there anything in BIOS to
that effect?

Thanks.
