: address wrong to not finding it at all (I believe it reports "No

It always didn't find it, you just got lucky before.  The no station
address in CIS means that it can't map the CIS.  This means the 'it'
isn't dc, but rather 'cbb'.  cbb's ability to map memory is kinda
flakey on some machines.  You have one.  You need to set
hw.cbb.start_memory to a value that makes your laptop happy.

Yes, this sucks, but it is a symptom of the deeper problems with the
dynamic allocation of resources in freebsd pci code.
