I hade some frezes as well with Ubuntu 9.10 64-Bit and 10.04
The problem was as followed:
As I started to download (in my case it was by JDownloader) after a while the whole system freezes.
I checked My RAMs and one seemed to be faulty but as I changed it to a new one the problem was still up.
We I used one single 1024MB and it worked perfect (each of the stand alone)
As soon I entered the second one the freezing problem is back.
I've seen at some forums threads, they had problems with the same wireless card as I use (Netgear WN311B).
For addition the same Netgear card was running fine on an other PC with Ubuntu 32-Bit
I was using the Broadcom driver by the proprietary drivers.
Now I changed the Wireless-card to a plug and Play (out of the box support) and all the freezing problems are gone.
I don't think the card is faulty, Probably something with the RAM addresses?
I have no idea, but the fault can be rebuilt.
