[Cerowrt-devel] periodic hang of ath9k

[R.]

Hello David & list,

Do you think we could get a build with CONFIG_PACKAGE_ATH_DEBUG
enabled? I've been following OpenWRT ticket #15320 and it looks like
this would be the way to go in order to get field logs of WiFi issues
from end-users.

In the meantime, here's the latest WiFi failures on my end (running
CeroWRT 3.10.44-6) -- recovered within two minutes:
