Description of problem:
We have a hardware platform with a csb5 chip below a PCI hot-plug slot.  The kernel has the csb5 quirk functions (drivers/pci/quirks.c) tagged with __init section marker, so these are discarded after system boot.  Unfortunately, in a hot-plog environment, we need these to be persistent functions, so __devinit is a better tag.  I have already submitted this request to the PCI Hotplug maintainer, Greg Kroah.  He has accepted my patch, and it is present in linux 2.6.12-rc5.  So in effect, this report is simply a request for a back-port of that patch.

Version-Release number of selected component (if applicable):
kernel-2.6.9-5.ELsmp

How reproducible:
Always

Steps to Reproduce:
1. Bring down Stratus platform hotplug slot 4.
2. Bring up Stratus platform hotplog slot 4 (kernel oops)

Any other machine with a csb5 below a hotplug slot will suffer the same fate as well.
  

Actual Results:  Kernel oops.

Expected Results:  Successful PCI enumeration and chipset init.

Additional info:

This is the acceptance letter from the PCI Hotplug maintainer, Greg Kroah:
