Interesting, all the pm_tests work. Even core. But when I switch it to
'none' it locks up.
If I just remove the ehci_hcd module, it suspends fine, so the issue is
with this module (or some usb device). There seems to be two devices
under ehci_hcd, and I played with the script to only unbind one at a
time. If I only unbind one (either one) it still hangs. I need to unbind
both for the suspend to work.
Without the script, here's the dmesg from the suspend to resume using
pm_test == core.
