viafb-camera: Funky IRQ

[Yioryos Asprobounitis]

I'm trying to use ffmpeg/ffplay (version 0.6.3-rpmfusion) on os885 to make a simple app for camera recording/viewing on XO-1.5.
The problem I have is that only the first or a couple of initial frames are showing/recorded and then it freezes there.
With ffplay -loglevel 7, kernel shows:

[  473.790518] viafb-camera viafb-camera: Funky IRQ 90200022
..... 
[  474.257107] viafb-camera viafb-camera: Funky IRQ 90200022
[  478.855311] viacam_quick_irq: 137 callbacks suppressed
[  478.860016] viafb-camera viafb-camera: Funky IRQ 90200022
.....  
[  479.155117] viafb-camera viafb-camera: Funky IRQ 90200022
[  479.322696] viafb-camera viafb-camera: Release: 329 hard, 167 thread, 162 frames
[  479.338337] viafb-camera viafb-camera: No frame 0, no buf 5 overruns 5

Could not find much about "Funky IRQ" on the web 
#10981 shows a similar kernel output but there is now follow up more than a year now. 
Anyone has some experience with ffmpeg and via-camera on the XO-1.5?
Thx
