Maybe, after all, I have a different issue. Today, after my first freeze I looked at the log (/var/log/Xorg.0.log.old). I ran through it, and I found (at the bottom) these lines:
(EE) A4Tech Wireless Battery Free Optical Mouse: Read error: No such device
(II) config/hal: removing device A4Tech Wireless Battery Free Optical Mouse
(II) A4Tech Wireless Battery Free Optical Mouse: Close
(II) UnloadModule: "evdev"
As I was googling "evdev", I found out that it's the module of all input devices (most mouses and keyboards). So in my case, that module can be the culprit. However, I still don't know what to do with it (how to fix/remove/replace/etc.), but maybe that can be a step discovering the origin of this bug.
Anyway, I propose everybody encountering the same freezes as me, to have a look at the log.
