Bit stuck here - anyone using LXC?

I seem to have it all setup according to what I can find online.
I can lxc-create a container, but when I try to run it, I get
this:

lxc-start: failed to clone(0x6c020000): No space left on device
lxc-start: No space left on device - failed to fork into a new namespace
lxc-start: failed to spawn '/sbin/init'
lxc-start: No such file or directory - failed to remove cgroup '/cgroup/xyz'

Sort of pulling my hair out - followed all the examples, but I get
that everytime I try to start a container - even an empty one running
/bin/bash. Google is only showing me one other instance of this issue -
with no real resolution, alas...

It's Debian Lenny with the debian package from sid installed (but I've
also tried compiling from source - identical results) Made sure the kernel
has all the right things in it - lxc-checkconf passes all test OK:

# lxc-checkconfig
--- Namespaces ---
Namespaces: enabled
Utsname namespace: enabled
Ipc namespace: enabled
Pid namespace: enabled
User namespace: enabled
Network namespace: enabled
Multiple /dev/pts instances: enabled

--- Control groups ---
Cgroup: enabled
Cgroup namespace: enabled
Cgroup device: enabled
Cgroup sched: enabled
Cgroup cpu account: enabled
Cgroup memory controller: enabled
Cgroup cpuset: enabled

--- Misc ---
Veth pair device: enabled
Macvlan: enabled
Vlan: enabled
File capabilities: enabled

So if anyone has any clues, I'd appreciate it!

Well, in-case anyone else gets this, it seems to be down the the
kernel version in-use. I was using 2.6.32, but when I went back
to 2.6.31, everything "just worked".

It may still be some obscure kernel setting, but I'll go through that
when I have more time.
