OK, I've done what you said but I don't understand anything.

$ sar -I XALL 2 1 | less
Shows that 0 interrupt is the problem (if I understood well).

$ cat /proc/interrupts
Show that the 0 interrupt refers to timer. (See screenshot)

What can I do ?
I had to disable lapic timer to prevent system from freezing everytime I don't use mouse or keyboard.
