andy git 06/15 suspend/resume observations

[Sean McNeil]

Actually, it seems a little less stable now. On 1 occasion I had it hang 
up while in suspend mode for a while where ping didn't work and I 
couldn't wake it. After a period of time (wasn't paying close 
attention), it woke up on its own and was OK. Now, it is stuck as usual 
with ping working but won't wake up.
