twin_test.bit (DIP's setup as per twin_test.pdf)
 Temporary Flash
Code:
 CM1: Running at 182.715256 MH/s
  CM1: Job interval: 17.805074 seconds
  CM2: Running at 181.279004 MH/s
  CM2: Job interval: 17.954064 seconds
 Notes
   CM2 (FPGA3) gets 50-70% less shares than CM1 (FPGA0) (Average Utility of 1.4-1.5 & 0.8-0.9)
   Also quite a few of the following errors on both FPGA's
Code:
   Watchdog triggered: 27276.511018 MHashes without share

The detected Mh/s is completly different each start of the worker, but after some seconds it will show you the correct Mh/s in the website of mpbm.
The Watchdog message come from my changes in the timings, the original timings wait ~3 times longer until it restarts the worker. It could be realy normal to get that message from time to time. But if you can watch the LED's and if you get the message when the orange LED is turned on, you will notice that then it turn off. this is the behavor I had on my board#0015. And my shorten timings make sure the board don't have the orange LED (no work/job) to long.
Im not 100% confident in this board at all;

If others are getting a U of ~5, you can see im getting about ~2 (cgminer reports similar figures)

 Notes
   First few shares ok, then;
Code:
  CM1: Got K-not-zero share eed4cb24
   CM1: Got K-not-zero share c1842661
   CM2: Got K-not-zero share 8c318943
   CM2: Got K-not-zero share 2fc4854e
Permanent Flash
  Not even detected
Please take a look at the mpbm webconfiguration, the interessting part are the invalid shares, they must be realy high on your board or the Watchdog messages come really often (orange LED turn on very often).
As you can see, its quite bad;

Perhaps its time to contact enterpoint to return this board for testing/replacement?
