Hi Alpha,

In which SFP cage have you tested the 10G module and the 1G module?

What 1G and 10G modules are you using?

Please share the kernel log of the working and non-working modules.

By the way, Russell King has just posted upstream kernel support for the 
Single Shot. You might want to give it a try.
