Bug Description
I'm running up-to-date Ubuntu 12.04.3 with the 3.2 kernel. I have a FreeNAS box exporting a number of NFS shares. My machine can boot once-in-a-while but I have problems on practically every boot, that I need to resolve by rebooting and trying again.
My fstab:
# /etc/fstab: static file system information.
proc /proc proc nodev,noexec,nosuid 0 0
UUID=2f6ca502-
nodev /ramdisk tmpfs defaults 0 0

The network between the two boxes is working perfectly over gigabit wired connection. I can always mount each share explicitly, it only causes failures a boot. My local network uses openwrt routers and has correct DNS setup for each machine.
My desktop (the machine affected by this bug) uses network manager with DHCP connection but I did try static IP before and it had no effect on the failure rate.
I've added a way to open an emergency tty (patched /etc/init/tty6.conf to start on startup) and inspected mountall logs (patched mountall.conf to have --debug, not have --verbose, have console log and not 'expect daemon'). I'll attach /var/log/
I have tried to debug this issue with jodh and xnox on #ubuntu-devel and got asked to report this and wait for slangasek. I can freely reproduce this bug and I can assist in debugging if required.

A log from a successful boot isn't going to tell me much. I need to see a log from a *failed* boot. :-)
How are your network devices configured on this client? ifupdown, network-manager?
