IVTV and Xen

[Jason <xen@jasonandjessi.com>]

Has anyone had any luck getting IVTV .61 working in xen (Im on 3.0 unstable changeset  Fri Mar 31
00:26:07 2006 +0100 9494:8a8361994904 because of some unrelated driver issues with another device).
I keep getting a DMA issue. If this is fixed in a later rev, I will upgrade but that will be a
pretty major undertaking on this particular machine, so I thought I would ask for others experience
first.   This is what I get when the module inserts, this ia DomU kernel BTW.
