Likely because you hit a firmware crash or some other problem. Hard to say without whatever was before that. Give you are mentioning linuxkpi_ieee80211_tx_dequeue, could have been this one? https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=275710 When you say you are still running release, that is 14.0? The freebsd-wireless list is generally a better place to to let us know about wireless problems. /bz -- Bjoern A. Zeeb r15:7
