udev created vbi0 and video0, there's no radio0 and video1. /lib64/udev/v4l_id /dev/.tmp-char-81:3 hangs in status D (uninterruptible sleep). I did not upgrade udev while upgrading kernels.

Hi, could you try the patches at <http://thread.gmane.org/gmane.linux.drivers.video-input-infrastructure/31187>?

I'll attach a single combined patch for convenience in testing. If that fixes it, then this is probably a duplicate of <https://bugzilla.kernel.org/show_bug.cgi?id=31962>.

Thanks for testing; that's great to hear.

To the bugzilla people: this is a dup of bug 31962.
