Subject2.6.38 regression caused by commit 415e12b
I'm having an issue with an xHCI (USB 3.0 host controller) Express Card.
This card works fine on 2.6.37, but on 2.6.38-rc5, when I plug in the
card, I get this output in dmesg:

This happens before the xHCI driver has a chance to start PCI
initialization.

I've been trying to bisect this on a slow laptop, so I haven't had a
chance to test with the latest tree from Linus to see if this is already
fixed. I'll do that later this evening.

I've bisected the issue down to this commit:

commit 415e12b2379239973feab91850b0dce985c6058a
Author: Rafael J. Wysocki <rjw@sisk.pl>
Date: Fri Jan 7 00:55:09 2011 +0100

PCI/ACPI: Request _OSC control once for each root bridge (v3)

Move the evaluation of acpi_pci_osc_control_set() (to request control of
PCI Express native features) into acpi_pci_root_add() to avoid calling
it many times for the same root complex with the same arguments.
Additionally, check if all of the requisite _OSC support bits are set
before calling acpi_pci_osc_control_set() for a given root complex.

lspci from a kernel where the Express Card works is attached.
