Hi All,
With one of the application (X11 and v4l2 based), I am seeing following kernel crash (Crash 1) with OMAP5 based system based on OMAP5_GLSDK_6.04.00.02 when I click on icon in app. I was able to fix it using patch to omap-gem.c from p-ti-linux-3.12.y(i.e. drm : avoid spinlock recursion in notify thread: http://git.omapzoom.org/?p=kernel/omap.git;a=commitdiff h=0f88f7ca8283f9407a17f150968c6fc1a980231chp=0421a5efd6e44bb29e3abe2dc80b4b2564083df9)
However now I am seeing another crash (Crash 2) after I left the system ideal after running the app.
Is this known issue? Could anyone give some pointers/suggestion to fix this?
Note: I have reverted changes from omap_gem.c as this
was causing similar crash and using the above mentioned patch instead (i.e.
drm : avoid spinlock recursion in notify thread : http://git.omapzoom.org/?p=kernel/omap.git;a=commitdiff;h=f968e920452aa3061fb1dfff1a55a55f8af60dde;hp=1bca805f90dc31eac5a2093074cf70fe1b806f55)
