Package: nfs-kernel-server
Version: 1:1.3.4-2.5
Severity: critical
Tags: upstream
I have using development environment for ARM (sama5d3) with root on NFS. Arm
donwload kernel and DTB boots and mount root exported by my computer with
Debian Buster.
I works perfect with Ddebian Stretch but stop with Buster. I tested many
kernels on ARM (latest 5.4.41 and 4.19.131) and nothing helps. In Virtual Box I
have Debian Stretch (works) upgraded to Buster (desn't work)
and upgraded to testing (doesn't work). Booting always end when kernel try
mount root on NFS with:
macb f802c000.ethernet eth0: link up (100/Full)

All is corectly exported but client never mounts. But when I boot Arm with root
on Stretch machine a try mount directory exported from Buster machine all works.
