After the latest import of ACPI sources, I get a load of these at boot time: ACPI-0252: *** Error: No object was returned from [\\_SB_.PCI0.PX40.UAR2._STA] (Node 0xc162a7c0), AE_NOT_EXIST I never had any real issues with ACPI before, aside from my power button not working for a short period of time while 5.0 was -current. Thanks
