[Bridge] Badness in local_bh_enable at kernel/softirq.c

[kylix]

Dear all:

    I builded a bridge on my embedded system, the linux kernel version 2.6.12;
the brctl version 1.0.6.
    I connect PC0 to eth0, connect PC1 to eth1, then I ping PC1 from PC0, It
is successful.
	But I got the errors blow from linux console when It forwarding ervry ethernet package.
    Can anyone help me ?
