# NousResearch/hermes-agent · Linux GPU-child init failure and CPU retry loop

## Open now

- Nothing open on GitHub.

A bug report and two related fixes addressing GPU child process initialization failures on Linux Mesa/Wayland, where a retry loop causes excessive CPU usage. The fixes introduce sandbox recovery steps and a one-shot software fallback to prevent indefinite looping.

## TL;DR
