I tested this for a while to be sure of the results. It appears that
with the mainline kernel 4.13.0-041300rc1-generic resuming from
hibernate works perfectly without the need to add the "acpi_osi=Linux"
kernel boot parameter. It worked correctly and reliably 100% of the
times I tried it (even repeatedly without a full shutdown).
Instead, even with the (almost) latest 4.2.0-83 Ubuntu kernel, more
often than not resuming from hibernate produces a blank screen after
unlocking the hard disk (for dm-crypt), unless the "acpi_osi=Linux"
kernel boot parameter is used. I must also say that, in any case (even
with such added parameter), sometimes resuming is not 100% reliable
because some devices seems not to wake up correctly (it happened with
keyboard or touchpad in my case, a couple of times).

Title:
HP ProBook 450 G1, resume from hibernate does not work unless
acpi_osi=Linux boot parameter is used
Status in linux package in Ubuntu:
Confirmed
Bug description:
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".
