Screen corruption with i.mx6 vivante driver after longer run time

On a Utilite pro with kernel 3.0.35 and Ubuntu 12.04.3 the following problem appears when using

the system for longer runtime and using more the 60% of the 2 GB RAM.

When continuing to use the system when these artifacts appear, most

of the time an axi bus error with screen freeze happens.


The current workaround is to use a modified xorg.conf file

with the accelerated fbdev driver (loosing openGL acceleration), but not the vivante driver.


Has this problem been seen on other i.mx6 based systems/boards with 2 GB RAM ?
