Comment 38 for bug 205653

If you are receiving issues while you are using any binary only bits (e.g. NVIDIA/ATI binary drivers, ndiswrapper etc) many folks will be extremely reluctant to investigate any issues your system is having (because they could lie in a binary only piece).

jaarik:
If you are using ndiswrapper I think you will have to see if you can find/file different bug report. While the hardware might be the same, your driver is different to that of other people in this bug report and as such while the outcome (crash) might be the same the cause may very well be different. Just for the record complete lock ups (where even sysrq doesn't work) are almost always kernel level bugs, X or broken hardware related issues. A userspace program like dbus is effectively unable to cause an issue like this.
