MSI never worked for me on Ventana. I have been using 4.2 extensively,
and now I'm switching to 4.5 (which doesn't work either).
Could it be a DTS (bridge) problem(?)
On 4.5, trying to use it with TW6869 frame buffer and GW5410:
TW6869: PCI 0000:04:00.0, IRQ 336, MMIO 0x1100000
TW686x 0000:04:00.0: enabling device (0140 -> 0142)
