I know you cannot just change the kernel for 64bit, i didth a 64bit install. The result whas the same problem as whit 32bit. installing the 686-PAE in 32bit results in the same problem. Every time i got a log out of my system.GregE wrote: You cannot just change to 64bit by changing the kernel.
I solved the problem whit a install of Debian Testing, and the problem is gone.
