Hm, should Docker maybe handle that more gracefully? If so we should report it upstream to Docker so it automatically sets the MTU correctly. :thinking: Alternatively, we could probably teach...

Hm, from [Bridge driver options](https://docs.docker.com/reference/cli/docker/network/create/#bridge-driver-options) documentation it seems that we can set the MTU when we create the `hassio` network. It should be fairly straight forward to add support for...

> About docker options, --help showing that there're only --enable-ipv6 is supported: Yeah I am aware. Creating `--mtu` is a suggestion how to implement this feature.

Besides the CLI also the actual feature in Supervisor is not yet released either (#6079 will be in 2025.08.2). Supervisor as well as the CLI plug-in updates are not dependent...

FWIW, this is the kernel boot log firmware information: Non-working, from https://github.com/raspberrypi/firmware/commit/4f43ba2f54dc6afddac54971a44f8ebb0c2e74d4. ``` # dmesg | grep firmware [ 0.052936] raspberrypi-firmware soc:firmware: Attached to firmware from 2024-11-11T15:50:32, variant start [...

So with the latter firmware (from https://github.com/raspberrypi/firmware/commit/3b48b3bd7d8bafefffd3e6d5722428dd41b6cc5f) and `initial_turbo=60` the hang happens too, so it seems to be related to `initial_turbo` then. > Does 'force_turbo=1' work ? I've tried that...

Just some thoughts: Since `config.txt` is stored on the USB flash drive, there must some thing happen with the new default (with turbo enabled). Presumably, USB initialization is now run...

I was able to reproduce the problem on the same device with a different USB SSD, in this case a Samsung Portable SSD T1. Same thing with Home Assistant, shortly...
