Same issue here on an acer aspire one AOA150. if I ever mount an SD card
I can't suspend the machine successfully even if I unmount it before
suspend, but it works fine as long as I never mount it. It started as
early as 2.6.32-rc3 (the first 2.6.32 kernel I tried) and still exists
with 2.6.33-rc7.

I get this message after a successful resume where I never mounted the
SD card.
