Do you have a .config, dmesg output or anything? I have here
| Linux … 6.16.0-rc1 #3 SMP PREEMPT Wed Jun 11 08:44:22 CEST 2025 armv7l GNU/Linux
| # lsmod 
| Module                  Size  Used by
| openvswitch           131072  0
| nsh                    12288  1 openvswitch

I have here 2GiB of memory but it also works if I reduce it to 256MiB.
