Seeing the exact same bug on my Pavilion 15-ab150sa, running Ubuntu 14.04.
Likewise, when I hold left shift (but not right shift) for 2 seconds the issue goes away for a certain amount of time. Hitting Caps-Lock brings the issue back.
Tried other versions of Linux (latest Mint, Fedora 23) and seeing the same issue - Windows works fine though.
On a somewhat separate note, have you seen any Wi-Fi issues? On my HP Pavilion the Wi-Fi seems to stop working intermittently, it requires a reboot to fix the issue.
