Installed sutton-precise-amd64-20130916-0 on the lenovo-v480c, and ran the s3
stress test, below two problems disappeared.
1.) System will fail to resume and start x altogether
2.) System will resume with applications in frozen state and unity
unresponsive to mouse-clicks.
But the third problem has been reproduced.
3.) System will resume however trackpad will be disabled.
And i found this problem has nothing to do with kernel or driver, since even
the trackpad can't work in the xwindows, it still can work well from the
kernel/driver side.
When the trackpad can't work in the xwindows, i executed "sudo cat
/dev/input/mouse0", it will transport lots of data to userspace when i
touch the trackpad.
