The DVC-5215 card Jean mentioned in his first post is a PCIe card.
The bridge visible on the card must be a TI XIO2000A with external
PCI arbiter. It allows to tweak some QoS parameters for PCIe traffic
that might be helpful.
Btw., for cards with PCI-PCI bridge the latency counter of the bridge
on the main bus should be set to a high value to give it an advantage
to flush its buffers.
