Video related Kernel Panic
It only seems to happen after several hours of sleep, and not if it's been asleep for just a couple of hours. Sometimes it will KP again on restart.
The KP is always accompanied by video distortion. Sometimes it happens immediately, and sometimes after a few seconds. This morning I was able to read a short e-mail message before it happened.
The Apple Hardware Test reports no hardware problems after both the basic and extended tests.
Yesterday, I did a full erase and reinstall of the OS. No luck. It happened again this morning.
I'd be very thankful for any suggestions as to what I should do at this point.
Here's the panic log, which seems to confirm that it's a video problem:
