Hi, (1) Colin has fixed the panic (after the firmware crash) so many people keep seeing. This may mean that you may now (contrary to before) try a service netif restart wlan0 to recover from such a crash. This changes is all the way to 13.2. I am still very pre-occupied with real life but I am hoping that I can get a possible fix tested and pushed during my Easter "holidays". (2) Along with enweiwu and cy the "startup problem" showing as "CTRL-EVENT-SCAN-FAILED" was debugged a bit more. We've for now backed out the rc startup script change and restored the old behaviour of wpa_supplicant with additional logging. This changes is currently in main only but will be MFCed to stable/13 in the next week most likely. If you etcupdate (mergemaster) and pull that change in I would kindly ask you to turn on debugging for wpa_supplicant and check if you see any log lines including "(changed)" [beware most should be "(no change)" along with IFF_UP in the line. If so please contact me. I still have a hypothesis that we may simply exploit a race in net80211 there which will need better fixing. (3) if you are using iwlwifi (or rtw88) I just pushed some locking changes into main. I would appreciate if you could test and let me know if there are any new regressions (they do not fix the firmware crash from (1) yet!). Lots of health, /bz -- Bjoern A. Zeeb r15:7
