Research direction
Start with the warning in net/core/netpoll.c and the brcmf_netdev_start_xmit entry point named in the log. Reproduce the issue using the provided modprobe netconsole command on a Raspberry Pi 4 connected through wlan0, then inspect the attached dmesg output. Done means netconsole starts without the enabled-interrupts warning or resulting oops.
