On my ThinkPad t43 suspend/resume works just fine in most cases, but
sometimes (once every ~20 suspends) it stops before turning off LCD -
the moon-led is turned on, but LCD is on as well and system freeze
What kind of debug can I add to track down the problem?
Can we printf some steps done on suspend (which device's suspend method
is called, etc.)?
