 in UEFI case

 I also have such a UEFI system.
 
 The main difference is that UEFI boot does not enable all devices and 
 our options to enable devices via ACPI do not improve anything.
 
 The symptom is (one of many examples):

                  Flags: PMEClk- DSI+ D1- D2- AuxCurrent=0mA 
 PME(D0+,D1-,D2-,D3hot+,D3cold+)
 
 - = CSM boot
 
 + = UEFI boot
 
 As I/O and MEM is disabled the drivers fail tho initialize. On my system 
 not any combination of the options
 
 options         PCI_INTR_FIXUP          # PCI interrupt routing via ACPI
 options         PCI_BUS_FIXUP           # fixup PCI bus numbering
 options         PCI_ADDR_FIXUP          # fixup PCI I/O addresses
 
 options         ACPI_ACTIVATE_DEV       # If set, activate inactive devices
 
 did give an improvement. I didn't see an BIOS options/knobs to force 
 UEFI boot to enable all devices like they are in the CSM case.
 
 The code for ACPI_ACTIVATE_DEV seems incomplete going by the comments.
 
 pciconf.c seems to contain code for enabling devices, but, if I remember 
 right, this is not called in amd64/UEFI boot.
