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. -- /Martin
