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:

I haven't had a chance to bisect yet.
Given that there wasn't any big new features added to the xHCI driver in
2.6.38, I don't think my code is the culprit here. Could it be a USB
core or ACPI issue?

Is the controller associated with irq 23?

I think it is, before the xHCI driver switches to MSI/MSIX. I'd have to
disable MSI in 2.6.37 to confirm.

Mm. Sounds like it's the hardware generating a legacy IRQ after you've
changed to MSI? Any chance this could be related to the irq
synchronisation patches?

Could be related, but I'm not sure that's the issue. I don't see any
messages at all from the xHCI driver or the USB core about the new host
before the "nobody cared" message appears (although it turned out I have
CONFIG_USB_XHCI_HCD_DEBUGGING turned off). AFAICT, the driver never
gets loaded. But if the xHCI driver failed in its init sequence...
I'll check.
