> I tried you patch, and this is what I get on 2.6.16-rc5: Well, thats a fun one. I'm assuming you tried to boot with a device plugged in. I'm a bit confused by the __reqest_region coming from usb_create_hcd - I quickly glanced at the function, and I don't see anything that would have called request_region / request_mem_region. However, there *is* a request_mem_region call immediately after the usb_create_hcd call in usb_ehci_au1xxx_probe, and I wonder that might be the guilty party. Matthias, any thoughts?
