I tried to reproduce it, but regrettably, the current upstream kernel croaks before I get that far with this: Unable to handle kernel paging request at virtual address a00000010400ab00 swapper[0]: Oops 8804682956800 [1] Modules linked in: Pid: 0, CPU 0, comm: swapper psr : 00001010084a6018 ifs : 8000000000000288 ip : [<a000000100ed8d60>] Not tainted (2.6.33-rc2-00302-gc5974b8) ip is at proc_net_ns_init+0x100/0x160 Guess I'll have to sort through that problem first.
