[Bug 147464] Re: Heavy network activity (eg: torrent/nfs file transfers) causes Hard System Locks and/or Network Freezes.

[Thomas]

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.
