[meta-freescale] Wandboard Quad experience (good!)

Fri Jul 12 17:07:22 PDT 2013

Chris,

This looks like it is coming from the Vivante GPU driver in:
drivers/mxc/gpu-viv/hal/kernel/gc_hal_kernel.c, line 1315.

How would I replicate this problem?

I did make one commit to this driver to init some uninitialized variables. 
These were throwing some errors during kernel compile.  Other than that, this 
driver is untouched by me.
