Is Network-Manager freezing my system?
Hi: I have a Lenovo T61p running an amd64 testing system. Yesterday, my system froze twice, i.e. became completely unresponsive, the caps lock LED flashing, as it does on this machine when it's frozen. (A quick Google search suggests that's a sign of kernel panic.) The only remedy is to hold down the power button until it powers down. The reason I suspect Network-Manager is twofold: (1) the freeze only happened when I had the machine hard-wired to my network, and (2) syslog showed lots of wlan0 activity - trying to connect, being denied a DHCP address - just before the freeze occurs. Has anyone else had a similar experience? I don't want to file a bug report against Network-Manager unless I'm pretty sure it's the culprit.

Patrick Hi, it was happening to me with an atheros chip and ath5k module. Removing NetworkManager in favor of WICD solved the issue, so I am pretty sure it was the trouble maker. Before the freezes I used to see a lot of rapid disconnect/connect cycles in the logs. This first happened on an Ubuntu Intrepid box (wife's box), and the issue is still there in Jaunty, so it would be no surprise that it shows up in Debian too. At the time Ub forums were full of likewise experiences with various wifi chips, in almost every case shifting to WICD solved the problem...

I'll see if it reproduces later (when I have access to my wired network) and try your suggestion. Patrick Funny you brought this up and I even said I had no problems.. WELL I was able to reproduce the exact same results here.. I was on the wireless network, plugged in to the wired network. As it was attempting to get an address ( 2 balls with spinning light) I right clicked to disable networking as wireless networking was already grayed out, thats when it froze. I was not able to SysRq+b to get it to come back and had to hard power down as well.. I spent about 10 minutes looking over the logs for anything useful but I couldn't come up with anything. Suppose it's bug worthy but I would like to file a report on the proper package. Anyone else?
