Bug#566547: linux-image-2.6.32-trunk-amd64: Segmentation fault during halt

[Aaron Barany <akb825@gmail.com>]

Here a the photo of the screen with the segfault. (http://akb825.com/images/halt%20segfault.jpg)

I couldn't figure out how to unload the fglrx module, since rmmod always threw an error saying that it is in use. However, if I boot in recovery mode it doesn't load fglrx, but it still segfaults if I call halt after logging in.

Thanks,
Aaron

It will be too late to log anything to a file.  But if you can take a
photo of the screen, please send that.

Please check whether this is reproducible if you remove the fglrx module
before shutting down.
