Hello, I'm trying to set up on a lenovo W540 mobile workstation I recently purchased. Things work well for the most part (including suspend/resume), however there's some error messages that I suspect are at the root of why the nvidia Xorg driver doesn't work, and possibly also at the root of why USB 3.0 won't work either. At suspend/resume, the following error messages show up: pci0: failed to set ACPI power state D2 on \134_SB_.PCI0.PEG_: AE_BAD_PARAMETER pci0: failed to set ACPI power state D2 on \134_SB_.PCI0.EXP1: AE_BAD_PARAMETER pci0: failed to set ACPI power state D2 on \134_SB_.PCI0.EXP2: AE_BAD_PARAMETER pci0: failed to set ACPI power state D2 on \134_SB_.PCI0.EXP3: AE_BAD_PARAMETER pci0: failed to set ACPI power state D2 on \134_SB_.PCI0.EXP5: AE_BAD_PARAMETER I suspect these might have something to do with the USB 3.0 system not working, though I don't have experience with either the ACPI or USB subsystems. Also, the nvidia Xorg driver fails to work, and causes a similar error message: ACPI Warning: \134_SB_.PCI0.PEG_.VID_._DSM: Argument #4 type mismatch - Found [Buffer], APCI requires [Package] (20130823/nsarguments-97) (the same message gets repeated about 10 times) Again, I don't have any experience with ACPI, but this looks to me like a vendor-specific quirk. Any advice on how to go about fixing/working around this? Thanks, Eric
