Hi Rémi,

It is great that you have a solution and thanks for posting the 
resolution - all too many forget to do the last step of posting the 
resolution information.

Our "wasted time" will become the next engineer's 60 second problem 
identification and fix, due to the power of gmane/google *and* the fact 
that you posted the resolution.

For me, your SDRAM problem was not a waste of time, it was an intriguing 
puzzle to solve.  In the words of Sir Isaac Newton, a smoother pebble or 
a prettier shell.

"I know not what I appear to the world, but to myself I seem to have 
been only like a boy playing on the sea-shore, and diverting myself in 
now and then finding a smoother pebble or a prettier shell, whilest the 
great ocean of truth lay all undiscovered before me."
