What about --no-pci-init-probe? I know it's long, but it is more descriptive of it's purpose to disable only the init time pci probe. I code and test and have it ready. I'm still working through internal processes to allow me to submit patches, but I hope to have that resolved in the next few weeks and at that time I can submit the patch. > > > -- > David Marchand >
