cma-512 crashes LE10 in RPi4 ! [SOLVED]

I've lost some hours to understand why my RPi4 started to crash at boot after installing newer le10 nightly builds.

After some tests I've noticed that the line in distroconfig.txt:

dtoverlay=vc4-kms-v3d,cma-512

Is the one to blame.

If I remove cma-512 from distroconfig.txt, Le10 works just fine.

I have a RPi4 with 4 GB RAM.

What could be happening ? (the previous le10 builds did not had cma-512 and also worked ok).

No one else had the same problem ?

Thanks

I'm not using it either!

It simply comes with every release from the past weeks,, but my rpi4 simply crashes at boot if I have it selected.

I have to manualy disable it, placing the sc-card in my pc and manually editing distroconfig.txt.

Is cma-512 needed ?

could it be possible to NOT being enabled by default ?

thanks

Did you by chance change gpu_mem in config.txt? If yes: don't do that, keep it at the default of 76 or you will experience crashes - LE10 needs lots of CMA memory, not GPU memory.

yes !

That was the issue.

Thank you very much.
