Hi,
During driver detach (while launching wifibox) I got a onetime panic.
Fullbacktrace attached.
This is with compat.linuxkpi.80211.hw_crypto disabled. So far I haven't been
able to reproduce it, so leaving it here just for reference.
How did you "detach"? Did you down the interface or run netif stop
wlan0 or ..?
To my uninformed eye, it looke like in fr 17, parameter should be a "ni" and
not an iv_bss.
ni and iv_bss should be the same but I see what you mean;
net80211 swapped the iv_bss away from under us.
Can you file a bug report Blocking 273621 for this. Feel free to just
point at the mail in the list archive for details:
https://lists.freebsd.org/archives/freebsd-wireless/2025-March/003038.html
That way we can track it properly.
Thanks a lot!
