Thanks Lori for a note about the bug with flickering. It's interesting that when my screen started flickering, the ACPI issue was fixed - until it broke again. Wondering if these are somehow related.
Also it seems this bug also concerns so far only Samsung users.
My laptop suspends and resumes ok - though it doesn't suspend on closing the lid even though it is not plugged in and power settings have been checked to be correct. Need to find/raise a bug about that too.
The freezing issue happens at random, 0-2 times a day. Suddenly everything just freezes, fan also goes on quite highly. Only way out is holding the power button for a long time. No solution from killing X or trying ctrl-alt-f1 etc.
