I just upgraded my home server from kernel 3.3.5 to 3.4.0 and ran into
some trouble. My laptop, a nfsroot client, will not run firefox and
thunderbird anymore. When I start these programs from an xterm, the

I have bisected this to

nfsd: add the infrastructure to handle the cld upcall
...and add a mechanism for switching between the "legacy" tracker and
the new one. The decision is made by looking to see whether the
v4recoverydir exists. If it does, then the legacy client tracker is
used.
There are two buts. First git will not revert this, so I can not confirm
this as the bad commit. Seceond, the previous step in the bisect
resulted in the client not being able to start X at all:
The bisect step before that:

nfsd: add notifier to handle mount/unmount of rpc_pipefs sb
In the event that rpc_pipefs isn't mounted when nfsd starts, we
must register a notifier to handle creating the dentry once it
is mounted, and to remove the dentry on unmount.
