I am also seeing this on my Thinkpad X200 running 10-CURRENT amd64:
pci0: failed to set ACPI power state D2 on \\_SB_.PCI0.EXP0: AE_BAD_PARAMETER
pci0: failed to set ACPI power state D2 on \\_SB_.PCI0.EXP1: AE_BAD_PARAMETER
pci0: failed to set ACPI power state D2 on \\_SB_.PCI0.EXP3: AE_BAD_PARAMETER
CPU0: local APIC error 0x40
