Public bug reported:

Hi,

For a few weeks, my laptop, an HP ProBook 6450b, enters Suspend state,
but upon resume, it restart fully the computer.

This is strange since it looks like the computer goes on Suspend mode,
but is unable to resume from it correctly.

It used to work, but I cannot say at which date exactly.
