Would you be so kind as to verify once again that this issue is not present on your hardware: SD card in, hibernate computer using "shutdown -h" resume computer and check task manager for the 3 errant processes. Users have confirmed this issue on quite a few machines, (one user tested this at an MS store and every machine had the issue) I just need to know if another device exchange is necessary, thanks.
I have it set to hibernate after 3 hrs and I never get this issue -But I do get it from a cold boot (sometimes) and a restart .
Can you verify that playing an mp3 from the sdcard fixes the problem? It does for me - I am curious if the problem is slightly different in other machines.
