I do not think a bisection is necessary. Your successful test of the
old regulatory code suggests to me that there is some kind of problem
with the CRDA database.

Luis - to fill you in, he can connect to an AP with a hidden essid
using the old regulatory code, but not using CRDA. There seems to be
some critical difference between them.
