I am also affected by this problem (or not?) using Natty (fresh install) on my new ThinkPad X220 with i7 and usb 3.0.

The proposed workaround by adding SUSPEND_MODULES="xhci_hcd" to /etc/pm/config.d/unload_module did not work for me.

I tried a lot and found out that suspend to ram works if I disable the options for charging usb devices in hibernate in the bios and manually unload xhci_hcd with modprobe -r xhci_hcd before suspend. I did not plugged in some devices for charging.

Suspend to disk is still not working. After writing the current state do disk my notebook turns off. After truning on it freezes showing some log output. Switching to a terminal is not possible. Only hard turning off is possible.

(By the way, it seems that wpa_supplicant is not resumed correctly since it believes that it is connected to an unreachable wlan.)

During trying I upgraded my kernel to 2.6.39-rc4.
