Looking into that a bit. I got three of these warnings and then the system panic'ed; hard lockup of the laptop, so no traceback. I'm rebuilding without netfilter conntrack support now, just to sidestep this, but I'll turn it back on for more testing. Attached is a dmesg from just prior to the panic. Same config as previous.
