Hello Nicolas,
It looks very similar to my first steps using FAI:
So you tried already adding :vers=3 to your cmdline after the
root=a.b.c.d:/srv/fai/nfsroot in your /srv/tftp/fai/pxelinux.cfg/HOSTNAME
which you created using fai-chboot ?
Is the nfs-server the same as the tftp?
Are you able to mount the nfsroot, when you booted via live-cd that particular
client? so /etc/exports is set up correct on the nfs-server?
Yes to both, I used fai-chboot -k nfsopts=-onfsvers=3 to build the tftp
file, and the FAI server hosts both tftp and NFS services.
The NFS root seems to be mounted, dracut says so (1st line of the log)
and showmount -a on the server also.

Hello,
I'm trying to use dracut in FAI 4.0.5 on a wheezy 64bits server, and the
initial boot on nfsroot quickly goes into kernel panic:
[ 11.578824] dracut: Mounted root filesystem

nfsroot has been successfully built using fai-chboot -SFv, and only contains an
empty /etc/fstab, and no /sysroot directory or link.
I initially thought that the problem was caused by nfs4 use of nobody:nogroup
to mount the nfsroot, but forcing the use of nfs3 is useless.
Could someone help me figure out what I am doing wrong?
Thanks,
