The report is expected behavior, since the xHCI driver doesn't implement PCI and USB bus power management yet. The xHCI power management code is still under development. I'm not sure if this code will be added to 2.6.32 stable, since it will add a lot of code to the driver. The code may need to be backported. Can you add this bug (or a link to the debian bug) to the kernel.org bugzilla? I'm trying to get all my xHCI-related bug reports and feature requests there.

The report is expected behavior, since the xHCI driver doesn't implement PCI and USB bus power management yet. That seems like a big problem if the xhci driver is going to be auto-loaded in desktops and laptops. The xHCI power management code is still under development. I'm not sure if this code will be added to 2.6.32 stable, since it will add a lot of code to the driver. The code may need to be backported. I doubt it is a candidate for 2.6.32 stable, but I think we would want to include it in Debian's kernel packages based on 2.6.32. Can you add this bug (or a link to the debian bug) to the kernel.org bugzilla? I'm trying to get all my xHCI-related bug reports and feature requests there. Will do.
