I compiled with these three patches, but it still crashed badly after I started
configuring and/or passing traffic on the 30 STA interfaces.
It is e1000e that first complains, but I still suspect ath9k because
my app was actively creating & configuring the STA interfaces when
this happened.
I can try a different system just in case..might be a day or two though.
The patches don't seem to make anything worse, and at least my
file-system wasn't corrupted this time, so maybe it helped..or
maybe I just got lucky.
