Would you believe last week's meeting was canceled, too? Not sure why the chair/co-chair are doing this but I'm finding it a little frustrating.

The spec can always be fixed later. -- ciao, al ----------------------------------- Al Stone Software Engineer Red Hat, Inc. ahs3@redhat.com ----------------------------------- _______________________________________________ iommu mailing list iommu@lists.linux-foundation.org https://lists.linuxfoundation.org/mailman/listinfo/iommu
