--- Comment #2 from Piotr Kubaj <pkubaj at FreeBSD.org> ---
There's really nothing I can do, ddb doesn't seem to work on mips.

Here's how to recreate this issue:
git clone -b releng/13.0 https://git.FreeBSD.org/src.git
cd src
make buildworld -j 32 TARGET=mips TARGET_ARCH=mips64
echo include ERL > sys/mips/conf/MYERL
echo options BOOTP >> sys/mips/conf/MYERL
echo options BOOTP_NFSROOT >> sys/mips/conf/MYERL
make buildkernel -j 32 TARGET=mips TARGET_ARCH=mips64 KERNCONF=MYERL
make installworld TARGET=mips TARGET_ARCH=mips64 DESTDIR=/mnt
make installkernel TARGET=mips TARGET_ARCH=mips64 DESTDIR=/mnt KERNCONF=MYERL
make distribution TARGET=mips TARGET_ARCH=mips64 DESTDIR=/mnt

Then enable NFS server.
Boot ERL using the following command (assuming DHCP):
dhcp; tftpboot 0 boot/kernel/kernel; bootoctlinux
