Bug#494384: first debian openvz 2.6.26 bugs
Sorry for the late reply, but somehow I haven't received any mail yet
(just saw the answers on the web interface).

Exactly.
I tried it again with 2.6.26.2 kernels on 686 and amd64 machines but the
problem persists.
With the kernel from linux-image-2.6.26-1-openvz-686_2.6.26-2_i386.deb
on the nfs server I get the same error as before.
It seems that nfsd and nfs fail to load:
# lsmod | egrep 'nfs|rpc|lockd|statd|idmap'
auth_rpcgss 34752 0
lockd 55016 0
nfs_acl 3680 0
sunrpc 163904 6 auth_rpcgss,lockd,nfs_acl
But NFS works if I use the non-openvz kernel from
linux-image-2.6.26-1-686_2.6.26-2_i386.deb.
Looking at the nfs client, I also get an error with the kernel from
linux-image-2.6.26-1-openvz-amd64_2.6.26-2_amd64.deb:

With a non-openvz kernel there are also no problems on the client:

auth_rpcgss 47520 1 nfsd

nfs_acl 7552 2 nfsd,nfs
sunrpc 197608 16 nfsd,auth_rpcgss,nfs,lockd,nfs_acl
(BTW why is the nfsd module loaded on a client-only machine?)
