hm, I wrote to the devs. I don't know the in-and-outs of the gemini ethernet driver.
The "shared" queues makes it special... and it's an interaction between at least two patches that caused this.

As for ext4-root:

I would be surprised if any of the storlink-like devices can boot off ext4 images without modification. Reason being here that the kernel cmdline is set to "rootfstype=squashfs,jffs2". So it will only check squashfs or jffs2 rootfs.

What is very common though is to use [[https://openwrt.org/docs/guide-user/additional-software/extroot_configuration|extroot]]-mechanism for the sort of thing you are describing. 

though it's not 100% the same as one "ext4" root-filesystem. It's because just the changes (i.e. installed packages, configuration modifications, new files) are being stored on "extroot" device. The advantage of doing this is that you can easily restore a device back to "factory" (i.e. initial openwrt) defaults (usually by the "10s press" of the reset button).
