jessie: nfsroots: "mount: Device or ressource busy"

[Gilles MOREL <contact@gilles-morel.fr>]

	Howdi,

  When I boot my diskless client, I got a message on console:
Begin: Running /scripts/nfs-premount ... done.
mount: Device or ressource busy
done.
Begin: Retrying nfs mount

  This message is repeated about every second for about three minutes before the mount actually works and the services start.

  I got messages in the server (debian) syslog:
Jul  9 08:36:03 Magnet rpc.mountd[31825]: authenticated mount request from 192.168.20.50:962 for /mnt/rootfs/stardust (/mnt/rootfs/stardust)                                                                                             │
Jul  9 08:36:03 Magnet rpc.mountd[31825]: authenticated unmount request from 192.168.20.50:962 for /mnt/rootfs/stardust (/mnt/rootfs/stardust)

  Here's the client's package version (debian jessie):
linux-image-amd64: 3.14+57
linux-image-3.14-1-amd64
initramfs-tools: 0.115

  Here's the server's package version (debian wheezy):
linux-image-amd64: 3.2+46
linux-image-3.2.0-4-amd64
nfs-common: 1:1.2.6-4
nfs-kernel-server: 1:1.2.6-4

  This problem happens since I updated the client's kernel to 3.14.
  From my point of view, these information are enought for you, but if you need more, contact to ask me.

  Thanks and regards,
