Please confirm this behavior with the current 5.1 beta.

I booted with dom0_mem set to 2G, 4G, 8G, 16G, 32G, 64G with 5.1 beta.  I did
not get the 'fatal opcode' error.   Dom0 boots and I can log in.

FYI, there is a difference in the system configuration I was able to use to do
these tests.   I was only able to run with one MSA1000, connected to one FC port.
