Additional info:
This time coincides with the daily crontab run.

This is a dual core system.  I'm using the nvidia drivers.

The system was installed on April 1 and has been stable since the install. This
morning I ran Seagate disk diagnostics and memtest-86 (1 full pass) - both pass.

I've attached a recent boot time dmesg in case that helps.

Only other hang on this kernel was when connecting a USB camera last weekend -
but nothing was logged on this previous occasion.  

Just before the bug the following was logged (probably one of the daily jobs):
