Comment 58 for bug 1518457

I can't reproduce with the older version of udev either. However, I think this is still a kernel issue, apparently triggered by an interaction with a recent change in udev. Finding the change to udev that causes this could be instructive for figuring out what the underlying kernel issue is, but I disagree that this isn't related to specific kernel versions - as demonstrated above I have the point at which this starts happening to within a few revisions of the kernel, with the same version of udev.
