Hi Omar,
Thanks for reply.
-----------------------------------------------------------------------------------------------------------
U : "What kernel is this? If non-mainline, I might try it out of
curiosity."
ME :
* code sourcery arm-2012.03-57-lite
* beaglboard xM rev C
* beagleboard kernel 3.6 (Beagleabord 3.6 branch) :
https://github.com/beagleboard/kernel/branches
* gstreamer 0.10.36 with plugins base, good
* custom FS (busybox only and base libs)
* ti LI23.8
* package gst-dsp 0.10.2 and the branch "next" for gst-dsp plugin
I did also make test with a "stable 3.2.30" and got the bug "scheduling
while atomic".
-----------------------------------------------------------------------------------------------------------
U : " CONFIG_TIDSPBRIDGE_CACHE_LINE_CHECK=y : I wasn't aware that now
gst-dsp supported this, might be time to update mine"
ME : I may repeat tests without this option. Can it cause troubles ?
Also here is how I load the module driver :
modprobe tidspbridge base_img=/lib/dsp/baseimage.dof
dsp_test_sleepstate=1
I did also tried with higher shm memory size (as seen in nokia luma
dspbridge package) : shm_size=0x500000

U : "I'm not seeing this with the fakesink decode"

There are no "scheduling while atomic" traces, so you may be right
about it is about omapfbsink.
I did also get those kernel logs :

Well I don't really understand them;
I can repeat the test without having kernel crashes.
-----------------------------------------------------------------------------------------------------------
Test on the omapfbsink with fakesrc gives no error and displays
correctly : gst-launch -v videotestsrc ! omapfbsink
-----------------------------------------------------------------------------------------------------------
With the following pipeline video starts and system blocks on the first
frames :
gst-launch -v filesrc
location=/home/mntfat/video_720x400_avc1_low_profile_aac.mp4 ! qtdemux !
queue ! dspvdec ! queue max-size-buffers=3 max-size-bytes=0
max-size-time=0 ! omapfbsink
But I get at the end theses logs :

So your right that is about omapdss, even if I don't understand why
this is the dspvdec0 that exits.
