mmc controller is probably confused. Try unloading its driver before
suspend. reloading it after resume to see if it *really* eats more
power.

Either usb problem or acpi broken after resume. Verify that
/proc/acpi/events work after resume, report to bugzilla.kernel.org if
not.

suggesting something is wrong there, too... but finding what went
wrong is almost impossible.
