Wish I could, but the way OpenWrt is designed, moving from one kernel branch to another is major undertaking often requiring months of tweaks 1,000s of patches, Makefiles, config files, etc. I have been reading up on NFSv4 and am wondering if there is a way to simply disable the callback function. Could that work-around this crash? Unfortunately, OpenWrt's nfs-kernel-server package does not ship nor use something like /etc/nfs.conf. At the link below you can see their init script to start nfsd. Many thank for any ideas. https://github.com/openwrt/packages/blob/master/net/nfs-kernel-server/files/nfsd.init
