I have not seen this particular INFO message show up again.
Therefore, I haven't tested your latest patch yet. I wanted to determine
whether this problem would occur often. If you like I can go ahead and
test the patch anyhow. I am currently testing mm5 + the pcmcia patch and
the hostap patch. I am looking into a crashing (system lockup) bug that is
triggered by removing my Linksys USB 10/100 Ethernet adapter. This
problem is 100% repeatable. I am working on setting up a remote
debugging configuration.

Would you like me to go ahead and test your latest patch?

Thanks,
Miles
