Hmm, strange. I have at least one test box with uhci_hcd that suspends (to RAM) and resumes successfully. Still, I've tested it with the hibernation and suspend patchset applied only. Simon, can you test 2.6.22-rc3 with the patches from http://www.sisk.pl/kernel/hibernation_and_suspend/2.6.22-rc3/patches/ applied?
