Hello,
It looks like the radios in my system had some serious problem for one reason or another
and stopped responding, and it hit a warning of interest up in mac80211, in this code:
if (new_state < sta->sta_state &&
test_sta_flag(sta, WLAN_STA_INSERTED)) {
int err = drv_sta_state(sta->local, sta->sdata, sta,
sta->sta_state, new_state);
WARN_ONCE(err,
"Driver is not allowed to fail if the sta_state is transitioning down the list: %d\n",
err);
}
So in case the driver is trying to do drv_sta_state, and it runs into -EIO. If we are going 'down the list',
should we force driver to ignore the EIO error and return success?
I think this is the pertinent set of logs related to this failure (several radios were failing
concurrently I believe, so possibly some logs are jumbled).
