RE: kernel panic in wireless-related sysctl walk

Hi

I have a Lenovo T510 running FreeBSD-12 STABLE. After configuring for lagg interface (combined from em - Intel gigabit ethernet adapter and iwn - intel wireless adapter) I can cause the system to panic with sysctl -a.
Using either the em interface or the wireless I can safely use sysctl -a, the system does not panic.

best regards

I have a oldish Lenovo R500 Notebook running FreeBSD-12 STABLE. I'm not sure what WiFi Interface driver the system is using right now; the WiFi is combined with the NIC to form a lagg-interface. I can 100% reproduce the crash described above via "sysctl -a". Just in case the phenomenon I discovered shortly after Christmas is of the same source as the initial poster has reported, how can I be of help? The system is a "pkg system"
completely, so I have to switch on debugging without kernel rebuilds. Any advice?

Kind regards,

O. Hartmann
