I have a test regress/sys/net/wg that configures a wg(4), sends some traffic, and destroys it. I have never seen this bug. There must be something special to trigger it. If it happns again, could you send an 'ps axlww | grep ifconifg' output? Then we see the wait channel where it hangs in the kernel. $ ps axlww UID PID PPID CPU PRI NI VSZ RSS WCHAN STAT TT TIME COMMAND The WCHAN string can be found in the kernel sources and gives hints. More sophisticated would be to break into ddb and show the kernel stack trace of the ifconfig process. If you want to do that, I can give some advice. But I recommend a serial console for that. Any idea what you did specially to trigger the problem? bluhm
