Hi Greg, I was trying to kexec boot to a 2.6.15-rc5-mm1 kernel with USB builtin(same specifics as above), and it failed again at the USB initialization. But if I revert the gregkh-usb-usb-ehci-updates-driver-model-wakeup-flags.patch, from the mm patch set, it works fine. It worked fine on 2.6.15-rc5 though. Any thoughts on what could be going wrong?
