Oh, well... It's impossible to completely fix softmac race issues.
I am _not_ going to rewrite huge parts of softmac to get locking
working. If you want this to be fixed, please hack up a solution by
yourself. I'm really not going to do more work on softmac. This
has various reasons. 1) I cannot reproduce all these bugs I'm hunting
2) Time is spent better at d80211 or other projects.

But to debug the problem:
Why do you get deauth messages? Broken AP?
I'd say that it's _correct_ behaviour to stop working
after getting a deauth ;). wpa_supplicant is responsible to re-auth.
Why doesn't it re-auth? Or does it do and it just doesn't work as
expected?
