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
