Bug ID: 91618
Summary: [Regression, bisected] System hang during hibernation
on EeePC 1015PE
Product: DRI
Version: unspecified
Hardware: x86 (IA32)
OS: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: DRM/Intel
Assignee: intel-gfx-bugs at lists.freedesktop.org
Reporter: eugene.shatokhin at rosalab.ru
QA Contact: intel-gfx-bugs at lists.freedesktop.org
CC: intel-gfx-bugs at lists.freedesktop.org
On ASUS EeePC 1015PE with the kernel 3.18 and newer (at least up to 4.2-rc6
inclusive), 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
The laptop has Atom CPU N455 and an integrated graphics controller (PCI ID:
8086-a011-1043-83ac) managed by i915 module.
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.
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.
Detailed information about the hardware, as well as dmidecode, logs and other
