And this is in code that is not specific to RAID at all, so if there really were bugs there, we would expect to have seen them well before now. I really looks to me like a hardware problem. Some how various bits of memory sometimes have bad values and cause a problem. How long did you run memtest? I would suggest running it for at least 24 hours, because my best guess is that it is bad memory, even though your tests so far don't show that. Is it possible for you to place 'mix and match' with another machine? i.e. swap the memory and see if it still fails. Then swap the processors. Then swap the mother boards. Then the power supplies... If not, you could try selective disablement. i.e. pull out half the RAM. If it still fails, put that back and pull out the other half. Pull out one processor and if it still fails, put that back and pull out the other one. Good luck...
