Today's testing at CSMC

[Mary Lou Jepsen]

Sounds like the suspend/resume bugs are about the same as C-build and
the software has slid back (regressed a little).   Just to verify - how
many units are you testing is it 10?  (what is the sample size - kim
says it's 42 which is an improvement on averages).  

The USB power switch failure is the exception - what happened - have we
seen this before?
