Video play on arm-Preemption disabled at <>

I am currently using an ARM Freescale processor board to perform video playback:

When I use the Qt Multimedia libraries over the application I get a Preemption before the video playback freezes:

BUG: scheduling while atomic: vqueue:src/642/0x00000101
Preemption disabled at:[<80101544>] __do_softirq+0x5c/0x3b4

However the video play back is smooth while using gstreamer pipeline without any issues:

gst-launch-1.0 -v filesrc location=/home/SampleVideo_720x480.mp4 typefind=true ! qtdemux !queue max-size-time=0 !vpudec ! videoconvert ! imxipuvideosink framebuffer=/dev/fb0

Qt multimedia system happens to trigger a kernel bug. It may be bug in Qt too, but no userspace application should be triggering a kernel panic. And that's what BUG: scheduling while atomic is. It's a driver bug somewhere in the kernel code, possibly the video driver for the board. Probably gstreamer has a workaround for that kernel bug, or does something differently and the kernel bug isn't hit. But it's definitely a kernel bug, no doubt about it.
