It's probably the b0rked PCIe hotplug support. The driver is way too strict about things at times, and as a result it doesn't work "out of the box" on a huge number of Dell notebooks (and possibly others). Just create a file called /etc/modprobe.d/pciehp, and stick this one line into it: options pciehp pciehp_force=1 See if that works.
