I think this is a general issue not specific to ironlake nor HP machines but a wide number of other models like mine (old Dell XPS M1330) and some other guys' on Archlinux user forum including Sony Vaio laptops. I rolled back to 3.7 kernel and ensured the issue is not present in that version.

Thank you.

Upgrade to Linux 3.8.10-1 doesn't fix the problem.
