BUG: Dell Mini 9 wifi driver scheduling while atomic: dbus-daemon/1612/0x00090000

[Fraser Doerksen]

I tried to install the restricted STA driver for the Broadcom 4312 wireless in my Dell Mini 9 laptop, on a fresh install of Ubuntu 9.10 standard edition. After installing 9.10 I applied all updates with aptitude upgrade, then went to the Restricted Drivers and installed the STA driver for Broadcom/ Then the utility seemed to freeze up, my Gnome bars vanished (wallpaper remained) and the Restricted Drivers utility then lost its theming. It looked like Windows 2000 for a while, until the utility vanished. The system hung. I forced a power off with the power button and got the bug report msg upon login.

On my Mini 9 the symptom is a bit different:

I first enabled the free driver which didn't work (see https://bugs.launchpad.net/ubuntu/+source/linux/+bug/502433).

After a reboot, I tried to enable the STA driver, but the machine crashed while installing. A black screen was shown with the underline cursor blinking in the upper left corner, and a white hairpin mouse cursor remained on the screen. The touchpad and the keyboard didn't work any more, not even Alt-SysRq combinations (tried K, S, U, B).

After power off and bootup the free wifi driver was still in use with the errors described in 502433.

An addition to my previous comment:

I got crash reports about the following failures, but it's not clear to me whether they were caused by attempting to install the STA driver or disable the free driver, which also failed.
- failure to install dkms (missed the version)
- bcmwl-kernel-source 5.10.91.9+bdcom-0ubuntu5 (package bcmwl-kernel-source (not installed) failed to install/upgrade: package bcmwl-kernel-source is already installed and configured)
- fakeroot 1.12.4ubuntu1 (package fakeroot 1.12.4ubuntu1 failed to install/upgrade: package fakeroot is already installed and configured)

Apport refused to send the report about dkms since the report was broken. It would have sent the report about bcmwl-kernel-source and fakeroot but I cancelled them.

Hi Fraser,

This bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

If it remains an issue, could you run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux 466109

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.
