An easy way to identify whether the machine has this problem is:
booting to gnome environment, pressing ALT+CTRL+F1 to enter text console,
executing showkey, closing lid, waiting several seconds, opening the lid,
if following logs are produced, your machine will have this problem.

@cypressyew,
Could you please use sudo showkey -s instead of showkey -k to catch
the scancode? scancode is more important to solve this problem.

Please install latest alsa daily dkms, then redo the test to see if it
can fix this problem. If it can fix the problem, I am going to backport
the fix to ubunutu utopic kernel. It is difficult to backport the fix to
linux-3.13 since the fix relies on the pin quirk framework.
The fix for this
and one more commit 00ef99408b6cc8d86ca614ada8025aa3606860db
