The thing is the kernel did work for like a couple of reboots (installed lmde x64 here yesterday) and it worked for like 3 or 4 reboots.
Now i dont know what happened, didnt update nothing since last update.. disabled stuff like printing and bluetooth.. went back with the old kernel and enabled it, but it didnt help..
About installing the kernel, i also installed the kernel on my LMDE x32 and it was intuitive(image+headers of same version).
But for some reason, on the x64 version i cannot find image or headers for kernel..searched for "kernel" in synaptic and i got strange stuff..
So ty about the link, but it didnt help me in this situation
