After a bit more testing/twiddling, seems NETCONSOLE_NBCON could
improve things at least a bit for RT. I was able to cleanly log an irq
thread handling sysrq-c over a wired interface. That beats silence.
Wireless wants more than a wee twiddle w/wo RT or NETCONSOLE_NBCON.
The path of least resistance there is bounce to kworker. Oh well.
