[Cerowrt-devel] Issues with 5ghz after a couple of days' uptime

I had complete failure to respond on 3.10.32-10 and -11 after less than a
hour of uptime. I was assuming that it was due to my keeping the
configuration files, and that something had changed in OpenWRT head and/or
dnsmasq. I didn't have time to do another merge at the time, and had just
flashed back to 3.10.32-9.
When 3.10.32-12 came out I checked the files, and didn't find any issues
with the configuration files. I also haven't had any more hangs. I have
ipv6 through he, and syn flood protection turned on. No issues to date with
