acpi dump file
Hi
I have notebook asus x551ma (Intel HD Graphics - Bay Trail - Sandy Bridge);
I have running kernel(s) 3.18.20 and 4.0.9; Seems like they both have backlight
issue on wake up on my notebook; After suspend I can see OS is running but
there is no backlight (LED); I tried reboot many times but all the same :P
The console mode (ctrl+F1) is not accessible bacause of the error "Ignoring
BGRT: invalid status 0 (expected 1) " and blinking cursor below :(
I suppose something is wrong with acpi module but still I am not sure so I
attach the acpi dump (see attachment);
Please help to fix the issue or advise a more or less optimal workaround;
Thanks
