This commit caused my system to hang after ohci_usb was loaded. It was reverted in 2.6.26 after my report. Later Alan sent the fix for it which I have been testing. This commit (with fix) is scheduled back in 2.6.27.
This is regression because 2.6.26 + two patches mentioned above suspend and resume just fine.
