Last modified: 2009-10-16 02:17:28 UTC
Hi, Recently I got this great device : http://www.interprojekt.com.pl/minitar-mwguha-wireless-adapter-80211bg-54mbps-p-318.html As the site says, this device is fully compatible with Linux kernel v2.6.6 and after. But apparently, network-manager crash my whole system when I'm connect on my personal wireless network. I use wpa encryption. The problem is network manager because I can use wpa supplicant to connect my network, and nothings goes wrong. However, I am able to make network manager works well but it is not very practical. Three ways : * plug the wireless device before starting computer * or start computer without this device, kill network manager ( if it is launch ) , launch nm-applet on terminal and plug ONE time the device. No remove after and no plug in after I remove the old configurations, I purge network manager and reinstall it again...Same issue. Otherwise, computer is down, no way to switch to console mode , gdm is completely out, no response ... [ 14.249043] usb 1-2: reset high speed USB device using ehci_hcd and address 2 [ 14.381835] phy0: Selected rate control algorithm 'pid' [ 14.458081] zd1211rw 1-2:1.0: phy0 [ 14.458117] usbcore: registered new interface driver zd1211rw [ 14.466144] udev: renamed network interface wlan0 to wlan1 So I want to put useful log here, what is the good way ? I'm on Ubuntu Jaunty Linux 2.6.28-13-generic network-manager 0.7.1~rc4.1.cf Thanks for help.
Hi, After some tests, I have more information about my problem. As I said this is very annoying because my wireless device is able to "kernel panicked" when I plug in before restarting my computer and I don't understand why. Maybe kernel scan device, give power, and had an unexpected response, I don't know. The second problem is to crash my ubuntu. To reproduce this bug, I need to plug this device, give my wap encryption key, and just when I got the connection established pop up, gnome-pannel freeze or disappear, I cannot move to console mode... So I think there is enough informations. I attached some log file, syslog lscpi, kernel version... Thanks.

/var/log/messages shows this is a kernel panic; it's likely a bug in the kernel driver for your wireless device. Please re-file with launchpad against the Ubuntu kernel with details of your hardware. Thanks!
