Which kernel version did you run before that?

The interesting part scrolled off the screen, please set
CONFIG_STACK_BACKTRACE_COLS=2 and try again. The last thing I
can see is ipt_do_table, if you are using connlimit in LOCAL_IN
its most likely that, the version in patch-o-matic is not
compatible with current kernels.
