Oops. Yes I did. I _thought_ I have Rev-C (3?) boards. Not exactly sure 
why I think so - perhaps that was what I ordered... And I really think 
the ones connected to automated test setup at the office are Rev-C.

Now that I tried to verify this - The one which I used to reproduce this 
issue (and now verify the patch from Tony) at home, seems to have say 
"PCB Rev6B" on PCB. However the u-boot says:

=>  printenv board_rev
board_rev=00C0
=>

but I have no idea where the environment variable comes from...

Maybe a stupid question - how to find out the exact revision?

Best Regards
