NetBSD armv7 9.0 NetBSD 9.0 (GENERIC) #2: Mon Mar 23 15:25:33 EDT 2020  root@armv7:/usr/obj/sys/arch/evbarm/compile/GENERIC evbarm
>Description:
Since the final release of NetBSD 9.0, I have not been able to boot from it on my Odroid-HC1.  However, I can boot from RC1, and have been able to compile the RC2 kernel and boot from it.

I have tried narrowing down where the problem lies and think that I've found it.  In particular, if I substitute /usr/src/sys/arch/evbarm/fdt/fdt_machdep.c from the RC2 source files to the final release source files and recompile the kernel, the system will boot.  

I have not yet extensively tested this modified release kernel, but will continue to do so.  However, I thought that you should know about this ASAP.

Be well.  Take care of yourself in this difficult time.

any time I try to boot from the final release 9.0 kernel
