Description Peter Robinson 2025-10-16 20:52:02 UTC

In a previous release we had issues with GPU drivers not having enough memory and we fixed that for RPi4 generations by setting the CMA for those devices to 256Mb.

It seems we have a regression, either in the firmware or in the config file where all RPi devices are assigned 256Mb of CMA.

This is fine for devices with 1Gb+ of RAM but causes issues for devices with 512Mb of RAM such as the 3A+ or the Zero2W because 256Mb isn't enough to fit the kernel+initrd to boot.

The issue with either the config file or firmware needs to be bisected and fixed.

Proposing as a Final FE, this is obviously the kinda thing we should fix on the release images if possible.
