[Xen-devel] DomU panic in net_rx_action; changeset 7503:20d1a79ebe31

Posted this to -users a while back; no response, and I've observed it a second time (with fewer modules loaded), so now posting to -devel.

Per subject, this is changeset 7503:20d1a79ebe31. It's a little bit old, granted, but I've been keeping an eye on -devel and haven't seen anything that looks explicitly like a fix being applied.
