For the record, adding acpi_osi=\"!Windows 2012\" to grub command-line fixes the same problem on my HP ProBook 430 G1 with similar but slightly different VGA chipset (Intel Corporation Haswell-ULT Integrated Graphics Controller [8086:0a16]). Haven't tried the deb provided by Anthony in comment #31, but I don't suppose they would work, as the fix in blacklist.c seems to be vendor/product specific.

Could this be a more generic Haswell issue?

Attaching dmidecode and lspcpi on my HP 430 G1 system.
