Why does Doomsday trigger a fatal wl_cfg80211_scan error?
Hello,
Serious issues. Doomsday randomly (because I have not been able to find any pattern or log info) causes a hard lockup on my system, generating the following as a final log entry -
which is apparently a problem with Broadcom WiFi chips. This is not a simple crash or application error - this is a full lock up with dead screen, keyboard and mouse that requires a power off to get out of. This is apparently a common error elsewhere, but no one ever has the same system death I get.
Why does Doomsday even make calls to WiFi? There are no network settings within it that I can see. This is a Dell Studio 15 running Ubuntu 12.04 - doomsday.out below.

Comments
I can think of two reasons:
They're the drivers Canonical tell you to get and are, quote, "tested by Ubuntu developers". They are installed correctly according to what the OS tells me.
Now you've lost me. I can find no updater settings in either the engine or the shell. And I still don't understand why it would kill all display and input device function anyway.
Driver bugs, or some other system level incompatibilities between hardware components, may cause unexpected malfunctions like this. There is nothing Doomsday can do about problems like this.
One common source of problems is too much heat inside the computer, causing overheating of the video card or other components. Have you checked that there is no dust build-up and that you haven't overclocked anything too much?
Also, have you tried to ssh into your machine from another after it has hung? If that is still possible, it might indicate that the problem can be isolated into the X server.
