I upgraded my late 2009 MBP to lion last week and had a bit of trouble until i decided to do a clean install. The clean install seamed to clear up most if not all the problems I was seeing. Today I woke my MBP up from sleep and it was frozen and needed a cold kill by holding the power button. A message popped up saying this needed to be done (said it was a kernel panic???). After the laptop restarted I noticed right away that spotlight began to re-index. I am not sure what happened or if it is a sign of trouble to come. My MBP has NEVER crashed like that before lion. Coincidence?
