The problem is not the aeMB, it is how ISE is synthesizing it. We have been working on this problem and are very close to having a solution.

Well, it seems the aeMB guys are working on a new version of the the core. Maybe the new core will perform better.

I am not building the USRP2 FPGA, or have experience with ISE 12, but the errors you have are all related to BRAM feeding the aeMB CPU - more specifically RAM output -> Mux -> Adder -> FF, mostly with 7 to 10 layers of logic inbetween. Good luck debugging that portion of the CPU. Hopefully you can achieve timing closure.
