Comment 125 for bug 286285

Nicoco - Yes, you do need to report a new bug unless you are absolutely 100% certain that you are experiencing the same bug as the one described in the original bug description, otherwise your problem will not be fixed and you will just make this bug report even more confusing than it already is.

After looking at the warning message in your dmesg, I very much doubt you are experiencing the same bug as this one.
