@davidc502 can miniupnpd be compiled with IGDv2 disabled in future builds. I have been using r6565 and IGDv1 miniupnpd from this thread. My WRT1200ACv2 has been running your builds since r2695 with no other problems.
r6781 has resulted in reboots, however I have loaded the older miniupnpd IGDv1 module immediately, so there may have been compatibility issues.
