Thanks for the patch :) I will test the patch ASAP. Anyway, while the 
fix seems "simple", I am sure it wasn't easy to track down the real 
problem. Checking briefly (by eye, not via debugger or tons of printf() 
), one will skip those lines because he/she will think the function  is 
invalidating the correct physical address (returned 
cpu_get_phys_page_debug() ). Great work!

NB: Althought it is a bit late, but it's never too late...Merry 
Christmast!
