                   ^^^^^^^^^^^^^^ dirty?

This kernel is not using the patches we sent.
No, but they didn't make any difference. I tried with all 3 applied, 
then backed them out one by one. That was the state when I posted before.
Well, this is a completely different warning.

Here are the dumps with all 3 patches applied:

b43/1997 is trying to acquire lock:

ieee80211_scan_completed+0x130/0x2e1 [mac80211]

but task is already holding lock:

ieee80211_scan_completed+0x130/0x2e1 [mac80211]
