I havn't seen this problem. Can you reproduce it at will?
If so, could you guys please try the nmi watchdog?

Add nmi_watchdog=1 to the kernel commandline in the bootloader.

Boot with that and wait a few seconds after the hang and see if it
prints out anything. Write that down (using a serial console is
recommended) and run it through ksymoops and post the output to the
netfilter-devel list.
