This is not an option on my kernel, I assume these options change between 
kernel releases.  Have a look at your /usr/src/linux/Documentation/admin-
guide/kernel-parameters.txt for pcie_ports options.  I suggested trying 
'auto', because it will only use PICe services if allowed by the BIOS and 	
Håkon mentioned he'd been tweaking his BIOS settings.
