Will do, but check perhaps for some 64bit uncleanes in the scatter gather stuff that got enabled in 2.6.13 because of the GPL'd Adaptec firmware, as I recalled some skb related stuff.
There is an easy way to disable the firmware and pretty much all the changes that went into 2.6.13: load the starfire with enable_hw_cksum=0. If you can easily reproduce this problem, try doing the above and see if you can still hit it. Maybe it's a newly introduced problem in the upper layer's SG--your other network driver simply isn't using SG so it's not affected.
It's very suspicious that the bug would be in skb_checksum_help(), since the starfire driver doesn't do anything with the skb before handing it over to skb_checksum_help(). It would mean that the upper layer handed an invalid skb to the driver, or that we have some random memory corruption somewhere.
Thanks, Ion -- It is better to keep your mouth shut and be thought a fool, than to open it and remove all doubt. - : send the line "unsubscribe linux-net" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
