ECS Exit code: 132 on Graviton3

Question

I running my app written in Rust on ECS backed by Graviton3 EC2. 
It runs as expected.

After my attempt to optimize compilation using processor specific things 
`RUSTFLAGS="-C target-cpu=neoverse-v1 -C target-feature=+sve2,+lse"`
the app starts even prints some Wellcome output and stops with Exit code: 132.

I started separate EC2 with Graviton3 processor. Installed Docker there and same app with same dokerfile works there like a charm.

Is there som additional tuning required to use +sve2,+lse on ECS?

Accepted Answer

This was also asked in https://github.com/aws/aws-graviton-getting-started/issues/370, and the answer is for ECS you need to provision your EC2 cluster with this AL2 AMI: `amzn2-ami-ecs-kernel-5.10-hvm-2.0.20240409-arm64-ebs` to get the proper kernel support for SVE.  The default AL2 ECS AMI uses the 4.14 kernel which does not support all the hardware features in Gv3.
