The touchpad attached to that bus works > perfectly fine after resume. Interesting that the touchpad works. From a first look, I can't tell why there is the high CPU load. Analyzing the call trace, I can see a flaw in the designware PCI driver, though. It uses UNIVERSAL_DEV_PM_OPS(), but should use SET_LATE_SYSTEM_SLEEP_PM_OPS() like the platform driver, so it will be a bit later and allow regular devices to suspend. Andy? Jarkko?
