Was there a USB device plugged into that controller? Two days ago I ran 2.6.27-rc6 plus gregkh-all-2.6.27-rc6.patch from http://www.kernel.org/pub/linux/kernel/people/gregkh/gregkh-2.6/ on my laptop, and it suspended with no problem. Can you try the same kernel? If you still run into problems, post more of the dmesg log (with CONFIG_USB_DEBUG enabled, of course!).
