Subject: 2.6.28(.1) and netlink: scheduling while atomic

Hi,

The new netlink interface allows to add NAT directly to a conntrack entry.
If it is used when the moudule nf-nat-ipv4 is not loaded in, it results in 
crash:
BUG: scheduling while atomic
It is in the kernels 2.6.28 and 2.6.28.1 in the function 
ctnetlink_parse_nat_setup(): it calls request_module() which causes the 
problem. If the module is already loaded, then there is no problem.

Regards:
K. Gy.
