acpidump output

Without any custom options my system boots, but it is unstable: screen
sometimes flickers, garbage appears in framebuffer, touchpad not always works
and sometimes kernel even crashes at boot time. With acpi=off everything boots
and works stable without any flickering and without garbage in framebuffer.
I've tried to boot with `acpi=ht`, but issues were still here.
