This is because of some unmap races in current grant-table code, allowing mapping domain to theoretically use a stale mapping in its TLB for a very short time after unmapping the foreign page. So, this crash indicates that you have not given any I/O-memory access privilege to the backend domain. Have you actually given it access to the Ethernet PCI device and its I/O memory and I/O port resources? -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
