We tried to move our Natty clients to Oneiric but have a severe show-stopper bug. Oneiric seems to have a problem with nfs. We use nfs for our home-folders with strict permissions. nfs4-server is running solaris.

As said no problem on natty, just with oneiric. Oneiric is running fine some minutes, then in the dmesg we get such output:
