10.27.1.254 (the address that the client connects to) is provided by
Heartbeat and is a virtual IP split across bond0 on the NFS server and
another interface on another NFS server.
Please let me know if you require any further information, thanks for
the help.

Bug#495946: initramfs-tools: potential race condition between nfsmounts in fstab and network interfaces
Package: initramfs-tools Version: 0.85i Severity: important On a server with three e1000-based cards, I have configured eth0 and then bond0 which uses eth1 and eth2. I have an NFS share that requires mounting on boot and uses the network attached to the bonded interface. If eth0 is listed first in the /etc/network/interfaces file, the system tries to mount the share before bond0 is brought up and times out as a result (although the timeout appears to be 7 minutes, not 180 seconds). If I place the "auto bond0" statement as the first statement in the file, the system works without issue. This issue can be replicated using SAMBA in place of NFS and is present after a base install with only a few more packages (such as ifenslave) installed. I realise that this may not be an initramfs issue, however I am unable to track it down any further. Please feel free to move to a more appropriate package if you think it may be required.
