Hi,
On ASUS EeePC 1015PE with kernel 3.18 - 4.1, there is a problem very
similar to the one fixed for Lenovo by the following commit in the
mainline kernel:
commit ab3be73fa7b43f4c3648ce29b5fd649ea54d3adb
drm/i915: gen4: work around hang during hibernation
When I try to put the system to hibernation, the hibernation image is
created, the screen turns off but the laptop does not turn off after
that (the fan continues to work, the leds are on, etc.) and the system
seems to hang.
The laptop has Atom CPU N455 and an integrated graphics controller (PCI
ID: 8086-a011-1043-83ac) managed by i915 module.
Detailed information about the hardware, as well as dmidecode, logs and
other data is available here:

Bisection of the mainline git tree pointed to the same "bad" commit as
it was for Lenovo:
commit da2bc1b9db3351addd293e5b82757efe1f77ed1d
drm/i915: add poweroff_late handler
If I revert that change, hibernation works well.
Regards,
Eugene
