Comment 8 for bug 774363

It is not fixed for me.

See attached dmesg output

(I don't know why second device is not in group video)

I have HVR1300 card: DVB-T + analog (with tuner)

When I launch tvtime (analog TV), the window opens but application hangs immediately after. Cannot be killed with kill -9 or Ctrl-C or stopped with Ctrl-Z in the terminal. The application is in uninterruptible sleep (see below, here two instances of tvtime were launched but this also happens when only one instance is launched)

From strace (see attachment), it is also possible to see that the problem occurs when tvtime tries opening /dev/video0

Also from a root console (just after unity has started so before running any process trying to access /dev/video*), just doing touch /dev/video0 or touch /dev/video1, the touch process enters uninterruptible sleep state and hangs.
