Subject: Re: 3.8.0-rc4+ - Oops on removing WinTV-HVR-1400 expresscard TV Tuner

Hi Chris,
  try to include in kernel only acpiphp and omit pciehp. Don't use modules but include
them statically. And try, in addition, check whether "pcie_aspm=off" in grub.conf helped.

  The best would if you subscribe to linux-pci, and read my recent threads
about similar issues I had with express cards with Dell Vostro 3550. Further, there is
a lot of changes to PCI hotplug done by Yingahi Liu and Rafael Wysockij, just browse the
archives of linux-pci and see the pacthes and the discussion.
