Ahoj,
I encountered an error in etnaviv driver on one of my two very similar SBCs.
They have the same board design but slightly different HW configuration.
SW configuration/setup is the same for both. Including kernel configuration.
1. is based on i.MX6S, single core, 512MB RAM, parallel LCD.
2. is based on i.MX6DL, dual core, 2GB RAM, HDMI display.
System No.1 boots OK. I can run kmscube and HW acceleration works.
System No.2 does not boot until I disable etnaviv driver in the kernel.
When digging deeper where the problem might be I found those two threads
[1],[2]. None of these apply to me. CMA is enabled and I do not specify
fixed CMA regions in DT.
I get the same results on v4.18-rc2 and on v4.18-rc5.
Relevant parts of boot log:

The system does not make it to the login promt but it seems kernel is running
as I see a LED with a heart-beat trigger flashing.
Any idea what might be wrong? How to further debug this?
Thanks in advance,
Michal
