I would like to add a few things: - a previously suggested fix - passing idle=poll to the kernel - did not work for me at the end - the locks I have happen very periodically (somewhere around every 22-28 hours), as if the chip would die after a given amount of data transferred; I know this looks stupid but I thought I might mention it - I have about 1Mbit/s of (incoming) traffic on this interface: with short, very high peaks, as there is a MySQL server on the other end, receiving about 100 queries per second - unloading the sky2 module totally freezes the computer for me - Fagzal - 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
