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.
