kernel 4.1 - System hang during hibernate on EeePC 1015PE
Last modified: 2015-09-29 18:48:30 MSD
There is a regression in the driver i915 in the kernels 3.18 and newer, including 4.1.
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.
This is an upstream problem. Bisection pointed to the following commit as the first bad one:
drm/i915: add poweroff_late handler
If I revert that change, hibernation works well.
I reported the problem upstream, no reaction yet:
A similar issue was fixed in the mainline kernel some time ago for Lenovo laptops but not for ASUS EeePCs, see
drm/i915: gen4: work around hang during hibernation
Perhaps, there is a better fix than just reverting that offending commit.
I have prepared a patch to fix the problem, sent it upsteam: https://bugs.freedesktop.org/show_bug.cgi?id=91618
Fixed with a more generic patch in the kernel 4.1.8.
