Hello,

I'm using a custom board with an iMX6Quad.

I'm experiancing the following errors (visible through dmesg):

[ 414.734840] GPU[0]: AXI BUS ERROR, AQAxiStatus=0x51

[ 512.083442] [galcore]: GPU[0] hang, automatic recovery.

[ 512.083489] [galcore]: recovery done

Any idea about the reasons for such errors?

The problem is not systematic. I'm running a Wayland based HMI.

How do I know the meaning of values reported by AQAxiStatus.

Is there any way to collect more information about this issue?

The Kernel version is 3.14.28.

Thank you.

Salvatore
