There should be no overlap.... Let me check the log ...
(II) Host-to-PCI bridge:
(II) Bus 16: bridge is at (0:0:0), (-1,16,0), BCTRL: 0x0008 (VGA_EN is
set)
(II) Bus 16 I/O range:
[0] -1 0 0x00000000 - 0x0000ffff (0x10000) IX[B]
(II) Bus 16 non-prefetchable memory range:
[0] -1 0 0x00000000 - 0xffffffff (0x0) MX[B]
(II) Bus 16 prefetchable memory range:
[0] -1 0 0x00000000 - 0xffffffff (0x0) MX[B]
The problem is on the host bridge BARs again. I don't know what they
are supposed to do, you need to look at the bridge spec, but you
definitely need to hide them some way...
