Looks like the problems start with patch 3/4.

All tests were done with all 4 patches applied on the AP machine,
and it appears that works fine.  The station machine worked fine with
the first two patches, but when third was applied, only a few stations
come up and I get behaviour similar to that described in the first email,
but I do not see anything obviously wrong in dmesg...

Thanks,
Ben
