This is the line that triggers that panic, from
/sys/dev/acpica/Osd/OsdHardware.c:

    if (pci_cfgregopen() == 0)
        panic("AcpiOsDerivePciId unable to initialize pci bus");

Please report the dmesg from boot -v as that should help figure out why
pci_cfgregopen() fails.

Also, I think the following should be "\_S3":
   Name (\SS3, Package (0x04)
