The upstream bug is in Debian 11. The current version of RaspiOS, which seems to support booting from NFSv4, is a Debian 11 derivative. That means that RaspiOS has fixed it for Debian 11. Is it possible to copy the RaspiOS solution?

Status in klibc package in Ubuntu: Confirmed Status in linux-raspi package in Ubuntu: Invalid Bug description: I'm running `5.13.0-1011-raspi #13-Ubuntu SMP PREEMPT Fri Nov 19 18:40:23 UTC 2021 aarch64 aarch64 aarch64 GNU/Linux` and have successfully set up netbooting on my RPi 4B (4GB). When I do not specify a `vers=` in cmdline.txt, NFS version 3 is used. I'd like to move to version 4, but unlike the setup described in https://forums.raspberrypi.com/viewtopic.php?p=1751741#p1751741, I cannot get `vers=4` (or any sub-version to work): the console logs `invalid value for vers.` for whatever I try. Current working cmdline.txt: ``` dwc_otg.lpm_enable=0 console=serial0,115200 console=tty1 root=/dev/nfs nfsroot=192.168.3.101:/srv/pinet/root,tcp ro ip=dhcp rootwait fixrtc splash ``` Nonworking cmdline.txt: ``` dwc_otg.lpm_enable=0 console=serial0,115200 console=tty1 root=/dev/nfs nfsroot=192.168.3.101:/srv/pinet/root,tcp,vers=4 ro ip=dhcp rootwait fixrtc splash ``` To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/klibc/+bug/1954716/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
