So it looks like your LNK1 device is no longer working correctly (it is the 
interrupt line that cbb0 is attached to).  You can try adding some printf's 
into acpi_pci_link.c to see why it is not working.  Note that LNK1 wasn't 
listed in the list of LNK devices for pci0.  It may be that the _STA is 0x9 
rather than 0xb and that we aren't handling that status correctly.
