According to https://bugzilla.redhat.com/show_bug.cgi?id=435550 the

dual-buffer mode with dvgrab, but does so in packet-per-buffer mode.

(subject to retesting by the reporter)

The reporter found that dual-buffer actually works if memory is reduced to 2GB. So there is a DMA mapping/ IOMMU related problem between kernel and board somewhere. Patch withdrawn.
