--------------------+-------------------------------------------------------
 During runin test on 11.2.0 build os22, over four hours, there are 10724
 messages from the kernel of which most are apparently triggered by the
 camera test.

  * 7304 instances of ''viafb-camera viafb-camera: Funky IRQ 90200022'',
  * 1865 instances of ''viafb-camera viafb-camera: Funky IRQ 90200020'',
  * 1481 instances of ''viacam_quick_irq: N callbacks suppressed'', where N
 ranges from 12 to 118, with the most frequent value 39.

 The camera test does this:

 {{{
 /usr/bin/gst-launch v4l2src ! ffmpegcolorspace ! videoscale ! ximagesink
 }}}

 I ask:
  * should the camera test use another command, such as xvimagesink?
  * are there any configuration methods to suppress the kernel messages?
  * are the kernel messages benign?  If yes, this ticket can be closed.
