I'd like to confirm this bug. My setup is similar: amd64, BCM4318, Gutsy, ndiswrapper and kernel 2.6.22-14-generic.
Basically, the network connection is suddenly lost and then some programs cannot be started (e.g. firefox, thunderbird). Any attempt to reboot or halt hangs while bringing down the network interfaces. In my case, even ctrl-alt-delete doesn't work and I have to hard-reboot it. This happened sometimes after two or three days of uptime, and sometimes after just 30 minutes. The interesting part of my dmesg is attached. ** Attachment added: "the relevant part of dmesg output" http://launchpadlibrarian.net/10172975/dmesg -- linux kernel: [ 4909.813152] Unable to handle kernel NULL pointer dereference at 0000000000000018 RIP: (ndiswrapper/iwconfig) https://bugs.launchpad.net/bugs/151565 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
