It occurs with various processes but the first two lines are always the same:

[<ffffffff8034f030>] debug_smp_processor_id+0xe0/0xf0
Mar 28 16:32:25 tangerine kernel: [<ffffffffa049ad0e>] ipt_do_table+0xfe/0x5a4

[ip_tables]

I've reported it on preemtion because of the header line of the trace but maybe it is related to iptables.

Attached: my .config.
