NetBSD rpi3 10.99.2 NetBSD 10.99.2 (GENERIC64) #0: Sun Apr 2 15:06:06 UTC 2023 mkrepro%mkrepro.NetBSD.org@localhost:/usr/src/sys/arch/evbarm/compile/GENERIC64 evbarm
>Description:
10.99.2 from 02.04.2023 fails to find the root wedge using the root=NAME=netbsd-root argument passed to it from the bootloader. It works fine on 10.0_BETA. The only thing changed is the kernel itself. After answering with "dk1" during boot, it continues to boot fine (although asking about /sbin/init). This is a Raspberry Pi 3 installation using an official image of 10.0_BETA from https://nycdn.netbsd.org/pub/arm/

Why is it not reading the label "netbsd-root" properly comparing to 10.0_BETA?
After reverting back to netbsd.img kernel from 10.0_BETA official image it boots just fine:
