Re: 2.6.23 WARNING: at kernel/softirq.c:139 local_bh_enable()

eeing skb in interrupt context, which is not allowed, and in interrupt skbs are queued to be freed in softirq, but netcnsole wants to flush softirq freeing queue. That is a question: why? Removing zap_completion_queue() from find_skb() will fix the warning, but I'm not sure this is a correct

g already freed and thus not required to be copied. Frankly saying, it can be not the correct fix, but from code observation and test, perfomed by David <[EMAIL PROTECTED]> it is. Actually looking at this function I suspect it was copied from nf_nat_setup_info() and thus bug was introduced.
