So... one of the machines on which I track head got this, as well -- my (mostly-)headless build machine. (2 laptops, updated in sync with the build machine, did not panic. One of those also uses a wired NIC.) In my case, the failure occurred after updating from FreeBSD 16.0-CURRENT #547 main-n285122-3b373d484046: Fri Apr 17 13:15:23 UTC 2026 root@freebeast.catwhisker.org:/common/S4/obj/usr/src/amd64.amd64/sys/GENERIC amd64 1600015 1600015 to main-n285179-7e9d974bc023. (As noted, 2 other machines (so far) updated to main-n285179-7e9d974bc023 without issue.) For now, I will reboot the machine to stable/15 (so it can build packages for tomorrow's weekly update), but once that's done, I'm happy to poke at it a bit or try out a patch or three, given suitable clues. The panic appears "quite reproducible." :-} Peace, david -- David H. Wolfskill david@catwhisker.org See https://www.catwhisker.org/~david/publickey.gpg for my public key.
