I am having trouble with OpenWrt release (21.02.2) in trying to get the cfg80211 module to work when it is compiled with "Enable testmode command support" in the OpenWrt build menuconfig. When I test this module out on (with this module being the only change) on a working 21.02.2 install, it generates a kernel warning and then a null pointer dereference causes a panic and reboot.
Is testmode command support known to be problematic? It's happening on an armv7l system (mt7623). A kernel log follows (first couple seconds removed to let it fit in this post)
