Ok, now please try to explain me this

I had a running fine installation, with default overclock and a rii air mouse/keyboard.
I moved root to NFS due SD card corruption.
I do a nightly backup of the nfs export using lvm snapshots.
Plugins: Italian TV streaming and pelisalacarta.

Everything was fine for more then a week, whith xbian always on and hours of streaming.
Two days ago I had to shutdown xbian for planned AC interruption.
Now, xbian freeze few minutes after every reboot.
Screen blank, host unreachable and non response to keyboard

I started to restore backups and now I've reached three days ago with no success: xbian load fine with no errors on dmesg, then after some minutes hangs with all the leds on.
I removed the rii usb receiver and I tried two differents power sources with no success.
Now I will try to restore an older backup and as last chance the first copy right after installation.
In the last days I rebooted xbian almost 4/5 times with no issues.
It's really strange and annoying.
