[...] Thanks for your reply. I will try to understand how to use gdb on this context. (Any URI would be really appreciated.) Anyway I now understood that a dbe is a data bus error, so probably this is an error on the physical address, i.e. a kernel problem related to the mapping between vertical and physical addresses. Is this correct? Thanks, Giuseppe
