Public bug reported:
Tested on HP ProBook 450 G1 notebook with Linux Mint 17 (based on Ubuntu
14.04) on a lot of kernel versions up to 4.4.0-47-generic #68~14.04.1.
While resuming from stand-by works perfectly, resuming from hibernation
does not work out-of-the-box (after unlocking the hard disk with dm-
crypt, the screen remains black).
To make resume from hibernate work, the "acpi_osi=Linux" kernel boot
parameter must be used.
Using it successfully right now with kernel version "Ubuntu
4.4.0-47.68~14.04.1-generic 4.4.24".
** Affects: linux (Ubuntu)
