A while ago I also had random lock ups with no traces in the logs.
Some wise people on this list suggested I check the cooling, a
suggestion I ignored because I was convinced it wasn't the problem.
But after I'd run out of other ideas I got a spiffy zalman copper
mushroom shaped heatsink+fan, and some fresh thermal paste. Suddenly
the problem went away.

So I suggest getting some high quality thermal paste (cost < 10$) and
spend half an hour making sure the processor is thermally coupled to
the heatsink and fan. If it's not the problem at least it's not cost
you much in time and money.
