Hi, A couple things to try: 1) Add the following to /boot/loader.conf and reboot: debug.mpsafenet=0 2) Can you send me the dmesg output? 3) Recompile your kernel with the following options: options DDB options KDB If you can enable the serial console and log it, please do. Then when the fault happens, send me the output.
