Here's my tale for this resurrected thread. I have my iMac 24" (10.6.3) set to never put the computer to sleep and put the display to sleep after one hour. The screen saver (Flurry) starts after 5 minutes.
Four times since moving to Snow Leopard, when I arrive in the morning, the system is frozen - won't respond to mouse movement or keyboard activity. The first 3 times, the screensaver appeared for a second before freezing. This morning that did not happen - just cold and dark.
So I hold the power button for 20 seconds or so, then click it and the systems starts up. Console shows a kernel panic at the moment I moved the mouse:
Code:

The general console log doesn't show anything too weird except the entry from Mail shown below. Any ideas?
