Since I'm the bug reporter of bug #404927 too, I can assure you that this
was never fixed. I've this issue on 3 different machines using aacraid.
Has anyone confirmed that this bug was fixed? The fix provided in bug #404927
is the one I'm also suggesting and it was never merged. The fixed that was
applied to udev rules was a different and it doesn't fix the problem.
More information follow separated by === lines. Please be more specific
if you want even more.
