etnaviv-gpu 134000.gpu: MMU fault status 0x00000002 on i.XM6 Quad Plus

[Luís Mendes]

Hi Fabio,

Yes, the problem does also happen at least with Vanilla kernels 4.12.5,
4.12.8 and 4.13-rc6.
I've just compiled and tested with those kernels.

These kernels also show an additional issue which results in complete image
corruption right from kernel boot and before loading etnaviv kernel module,
as well as after loading X and etnaviv module.
Despite the complete image corruption, I was able to login into X by
entering the user password. During the log in and X session start the
system log also shows similar MMU errors.

Please see attached PDF with screenshots detailing the observed image
corruptions.
All these reported problems only happen on i.MX6 Quad Plus.

Regards,
Luís
