I hadn't done any git bisection yet, but with acb42a3 I started getting this:
(and only on i686 - x86_64 does not show these):
(This is with Xen, the other one is without)

The skge driver uses hardware receive checksum where it computes the sum
of the packet (but does not check it). This kind of problem happens when some
part of the call chain above it updates the packet but does not update the checksum.
A fix like the following is presumably needed for some part of this path.

bridge: correct IPv6 checksum after pull
Bridge multicast snooping of ICMPv6 would incorrectly report a checksum prob
when used with Ethernet devices like sky2 that use CHECKSUM_COMPLETE.
When bytes are removed from skb, the computed checksum needs to be adjusted.

No he's not saying that, he says somewhere we probably need a fix
"like" the commit he mentioned.
He did not say that commit fixes this bug.

Ayee. Sounds you guys have an idea about this bug then. If you want me to run
a test-patch I can certainly do so. Thanks!
