[Q] tilcdc: cannot allocate buffer

[Robert Kuhn]

Hi,

using the code from
https://github.com/dvdhrm/docs/blob/master/drm-howto/modeset-vsync.c
on my beaglebone black I get sometimes this error:

[ 7772.673057] tilcdc 4830e000.lcdc: failed to allocate buffer with size 5242880
[ 7777.663102] tilcdc 4830e000.lcdc: failed to allocate buffer with size 5242880
[ 7783.892790] tilcdc 4830e000.lcdc: failed to allocate buffer with size 5242880

When I restart the programm usually everything works as expected. What is the couse of this error?
