Yea, Hopefully @jnettlet can spare some time to look at the ClearFog. I’ve tried SERDES 17_5_2 with partial success (100g does not seem supported yet). I get ubuntu partially booted, and it does detect my 25G transceiver in one of the SFP+ slots from fs.com, but unfortunately there’s something still missing, as it dumps me to emergency console before reaching login prompt.
