Zeeb from comment #1) I'm describing the smallest test case I could find: 1. Boot FreeBSD-15.0-RELEASE-amd64-memstick.img from a USB drive 2. Choose "live system" at the first installer menu 3. Log in as root 4. ifconfig wlan0 create wlandev iwm0 5. ifconfig wlan0.50 create vlan 50 vlandev wlan0 inet6 -ifdisabled up 6. Once the machine came back up, I copied the dmesg output I'm working on the assumption that the dmesg output, which appears to captu= re the first boot, the crash, and the subsequent reboot, is not missing anythi= ng important. I can go back and photograph the screen after triggering the cra= sh if that will contain anything more. I did initially find this with an rc.conf equivalent, but there's no IP addresses here, nor is the wifi card connected to any SSIDs yet - although = it does crash in that case as well. I'm not sure why nothing is visible in the dmesg output, unless you're looking for lines logged by the /etc/rc.d/netif. --=20 You are receiving this mail because: You are on the CC list for the bug.=
