Martin, please step in here if your problem has come back...

After Martin applied my debugging patch, the problem went away. Last I
heard, he was going to boot back into a kernel without my patch to see
if it stayed fixed.

My guess is that it is be a screwy BIOS that is causing the problem
intermittently. Otherwise, I can't imagine how some printks could
affect the problem. It's not like this is happening in code where there
are SMP races.

I also checked around the office a bit to see if anyone else was having
memory detection issues on large memory x86 machines. No luck. I'd put
this into the "unreproducible" bucket for now.
