Hi
I recently updated my Precise desktop to linux-image-3.2.0-40-generic on my Lenovo T420 and I am experiencing hangs on boot.
It doesn't always happen - probably 80% of the time or more.
If I go back and book with 3.2.0-39-generic or older , I do not see this issue (it will boot every time).
the screen goes black and there is no disk activity. Only lights on the T420 are the power and bluetooth light
The T420 runs an Intel i& vPro processor
