Firstly I have no solution, only anecdotal advice... I had a similar problem on an older computer, the hard drives would lock up ( although the kernel was still running it couldnt load from disk ). And it totally confounded me until I remembered my system Bus was over clocked. I turned it down and the problems stopped. I replaced that box with an Athlon 1700 on Gigabyte KT400 board, adn I get the same spurious interrupt ( on boot ) as you, but I have had zero problems with my new machine. My guess is that the problem is with the Hard drives or the HD contoller. You should concentrate there.
