Known to me (who wrote the original implementation of the current IMQ device) and numerous people who were hit by them. IIRC it does some invalid skb refcounting hacks which result in crashes in certain scenarios - but I don't remeber the exact details. > I was considering using imq for our needs (not done yet), and from the > FAQ at http://www.linuximq.net/faq.html (item #3, "Is it stable?") it > seems there's no problems except of gre tunnels and locally generated > traffic... > > Googling for "imq linux problem" shows usual pile of various user > support questions (how to configure.. what did I do wrong.. etc), > but nothing relevant. The lartc list had lots of reports of crashes. I guess "imq crash" or "imq oops" will give better results. > So...

Current kernels include Jamal's tc actions and the ifb-Device, which obsolete IMQ anyway. - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
