Hi, sorry for the top post, on my phone.

Yes, your analysis is spot on I think. I've got a fix for this in my
jberg/mac80211 tree, there's a deadlock with a work struct and the
rtnl.

Sorry about that. My testing should've caught it, but that exact
scenario didn't happen, and lockdep for disabled due to some
unrelated issues at early boot,so this didn't show up... (I also
sent fixes for the other issue in user mode Linux)

Is that the fix you are talking about?

commit 79ea1e12c0b8540100e89b32afb9f0e6503fad35
"cfg80211: fix management registrations deadlock"

Right. I only have two fixes in that tree ;)

I'll see if I have anything else, and send it off to davem later.
