Zeeb <bz@FreeBSD.org> --- Hi Deb, interesting given this is a CNVio system. List scan would only show what's in the scan cache; ifconfig wlan0 scan would possibly trigger a new scan and further changes. Likely something else was going on at the same time given this is a net80211 state change. Haven't seen a panic in lkpi_iv_newstate() in years. On my system that offset points to a clause with a printf and a return() statement, which in theory should only be triggered in case of a Channel Switch Announcement (CSA). But nothing which should panic. I'll go and double-check offsets for 15.0-p2 specifically as well. Do you by any chance have the core.<n>.txt file matching that vmcore.last? If you do and it's significantly larger than 300 bytes, would you mind emailing it out-of-band to bz@, as it may have the kernel message buffer (dmesg) in it and we may possibly see if anything happened before that panic which is relevant. If it is around 300 bytes +/- a few hundred, then likely gdb is not installed and crashinfo could not create the report. I can help setting that up (and re-running) if needed.
