I suspect a power-down issue, or an invalid assignment by the BIOS.

Ohh, complication: These are the bus bridges on your multiport card.  You'll
have to find their bus number in /proc/pci and do
  pci-config -B <bus-number>
  pci-config -B <bus-number>
and look at the output for the individual chips.
The 'lspci', if you have it, might do this without as much mucking about.

If the device has ACPI power management (not all 21143 chips do), it must
be in ACPI D0 state, not ACPI D3 state.
