Hi,I can confirm this bug. I also couldn't find any logging done to syslog, kern.log or anything else. Crashes happened very infrequently to me, but updating network-manager to 0.7 made that the system crashed within a few minutes. It was suggested that this was when there was some wireless activity, which might well be the case. I have exactly the same wireless card as the OP. Deinstalling network-manager and installing wicd as user frontend to the network services solved my problems. There's also a related bugreport posted to the network-manager package (#527857)
