[PROBLEM] System freezes after a while

[rph-r]

Hi,
I found the offender:
after a kernel failure (probably due to daily hard shut down), I reinstalled a fresh moode, last version. I reconfigured all and tried, the bug was still present. Then I thought maybe it has to do with NAS, so I removed the network drive (on another RPi), and it works, no more freeze!
Hope it helps to fix it!
