Doctor, it hurts when I do this...

1) Define disappears - the hardware is no longer present or visible to
the OS? What does pciconf -lv look like in both failure and success
states? 
2) How does named fail? Can you restart named? What error messages are
output in both cases?
3) Where in the kernel does it stall? Can you break in with the
debugger?
