I have an issue driving me crazy which may be the same thing. I'm using Lucid with a Lenovo T61 laptop with the Intel PRO 3945ABG network card. When I try to connect to my WEP network at home, my computer immediately hard-locks -- no mouse motion, no keyboard control, nothing.
I've tryed switching to using WICD, which so far doesn't work for me -- can't acquire an IP address -- but at least does not lock up my laptop! I do think that this problem is in someway related to the kernel version, because I had the same problem when I was using Karmic but in my case I could work around it by selecting an older kernel when I restarted the machine. -- NetworkManager causes system freeze, lock up, kernel panic https://bugs.launchpad.net/bugs/336001 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
