Can anyone verify with RB112 to see if it is also effected by this?
No. The RB112 is working fine with .37. (installed it on 19 boards last night)
I do have to say i'm in a 100% routed environment, so if it affects bridge mapping to ether port, I can't say.
This sounds like the behavior I was seeing on the RB112 with the short lived .36 build of the software though.
For grins, try forcing manual duplex settings, that brought up the ether port on the RB112 after the .36 build.
