Any hint when this patch will be merged into -current? A Pi2 armv7 at
FreeBSD pelorus.zefox.org 16.0-CURRENT FreeBSD 16.0-CURRENT #34 main-n284745-6cc99baea607: Thu Apr  2 09:53:47 PDT 2026     [email protected]:/usr/obj/usr/src/arm.armv7/sys/GENERIC arm armv7 1600014 1600014

still crashes on shutdown

Thanks for reading!
