Summary0005932: Latest kali 2019.4 running kismet on RPi3 produces massive logs for rtl8812au driver until kismet crashes.
DescriptionRunning kismet on RPi3 with the latest upgrade of kali 2019.4, the kernel produces stack traces more often than ONCE EVERY SECOND, quickly filling /var/log/messages with many kilobytes of similar data.

Somewhat later, kismet stops with an error:

FATAL - Capture source did not get PING from Kismet for over 15 seconds; shutting down
ERROR: Data source 'wlan1 / wlan1' ('wlan1') encountered an error: Pipe
       client error writing - Unknown error: 32
Uncaught exception "deadlock: shared mutex lock not available within 15 (claiming write)"
Stack trace (most recent call last) in thread 16858:
ALERT: SOURCEERROR Source wlan1 has encountered an error. Kismet will
       attempt to re-open the source in 5 seconds. (1 failures)
ERROR: Source wlan1 has encountered an error. Kismet will attempt to
       re-open the source in 5 seconds. (1 failures)
0000001 Object "/lib/arm-linux-gnueabihf/libstdc++.so.6, at 0x76a1dd83, in
#0 Object "kismet, at 0x78b303, in TerminationHandler()
Uncaught exception "std::exception"
Steps To Reproduce1. Start kismet. It properly produces it's normal info about startup, detected devices, APs, etc.
2. tail -f /var log messages
3. wait for kismet to crash
Additional InformationThe errors logged in /var/log/messages look like this, from one of these to the next only the time changes:
