You could comment out that error message in order to see what else is
in the log. It is located in drivers/usb/host/uhci-q.c in the
uhci_result_common() function.

You could try running -rc3 instead of -rc2, although that probably
won't make much difference.

What USB devices do you have on the failing system? In particular,
what is 5-1? If you unplug it before suspending, does the problem go
away? (It certainly should!)
