Letux Kernel

Issue 591: 3.14: Tux missing on Boot-Panel

Reported by Nikolaus Schaller, Apr 10, 2014

only if we compile with device tree.
Compiling with old board file did work (at least up to 3.14-rc7).

appears to have something to do with panel drivers as kernel 
modules. So the fb is coming up too late (where the Tux already has 
been drawn)

Code to draw the Tux appears to be:

fb_show_logo()

http://lxr.free-electrons.com/source/drivers/video/fbdev/core/fbmem.c
#L663

We have to find the calling sequence and how it relates to DSS 
initialisation.

Simple idea:

put dump_stack() into fb_show_logo() and check how it is called from 
omap dss initialization (if at all).

Add some EPROBE_DEFER return at a good location...
