We're seeing DFS events too, in places where radar signals are *very*
unlikely to be the real cause. Currently running 7.6.130.0.
We believe we may be hitting CSCuq86269 and/or CSCut98006. The first is
fixed in 8.0.120.0 and the second in 8.0.120.1 (escalation build); we
obtained an escalation build recently and are planning to upgrade one or
two controllers to test it.

Same here. We are seeing false DFS events on 7.6.130.0 as well. Please let us

I'll second the false DFS events, or perhaps more accurately said "alleged" DFS
events. I'm working with TAC now to figure out whether we really have radar or was it
the upgrade from 7.6.130 to 8.0.120 that did it.

It has been a month and a half since we upgraded to 8.0.120.0 and have not
experienced any problems.

We have been running 8.0.120.0 on our 8510 HA Pair and haven't had any major
issues.
We had some strange behavior that we mistakenly thought might be
related to 8.0.120.0 but we finally found that the real issue was MAC
table exhaustion on switches in the Residence Halls. (The APs there
are in flex connect mode.)

the APs will randomly crash. The APs are primarily model 3500 and 3600. I
have been informed that the solution is to upgrade to version 8.0.120.0. I was
looking to see what others have experienced in there upgrade from 7.6.130.30 to
version 8.0.120.0.
