ReadyNas 6.2 (NAS locks up entirely)

Whats stupid is that the hardware is fine, its the new 6.2.x firmware that's broke. I was on 6.1.5 for a year and it never locked up. I have no apps running just a few Servers backing up to it and 4 USB drives I rotate each day on it to give me a second backup on the critical data. If we could somehow go back to the magical 6.1.x firmware Netgear would have no more support calls and we would all be a lot happier. I'm running the 104 NAS by the way and I'm back on 6.2.0 firmware but get lockups ranging from half a day to 3 days between them.
