There is persistent system hang after every attaching or detaching of AC power
on a running system. Nothing works till the hard restart. I see this in
messages:

I've also attached acpidump output. Is there something I can try to turn off/on
in uefi menu to make it working or it requires some kernel patching? I'm open
to any tests. Thanks.
