I tried another slot (there are only 2 pci slots on the mother board),
but the same thing happens. It required about 3 boots to get the
firmware to load. I hope it's not a problem in the RME PCI card itself.
You could try checking whether the PCI card is detected in the cases where
the firmware is not loaded. It is PCI and not PCIe?
Compare the output of lspci in the good vs. failing case and verify that
the PCI card is detected, because the driver will never load and attempt
to find the external interface if the PCI part of the interface is not
detected.
