The problem is that the interrupt controller's default for the cpu
parameter is 'Parent.any', which means it grabs the nearest CPU it can
find... which is fine for uniprocessors but ambiguous for
multiprocessors. I fixed this in our tree a while ago (probably just
after patch1 was released), so it will be in the next release. (Good
news: Nate & Kevin are working on putting together a 2.0beta2 release
that should come out any day now so that you can have all our bug fixes
to date.)
Meanwhile here's the patch:

Hi Lisa,
As mentioned by you, I have read the webpage. I was
trying something like -
"root = Root(clock = '1THz',
system = makeLinuxAlphaSystem(mem_mode, bm[0]))
root.system.cpu =
[AtomicSimpleCPU(),AtomicSimpleCPU()]
root.system.cpu[0] = cpu
what is it that you were trying to do with the above assignment? did
you ever define cpu anywhere? you've already assigned
root.system.cpu[0] by doing the "root.system.cpu = [AtomicSimple....]".
cpu.connectMemPorts(root.system.membus)
cpu.mem = root.system.physmem
root.system.cpu[1] = cpu2
cpu2.connectMemPorts(root.system.membus)
cpu2.mem = root.system.physmem "
in fs.py file. But I am getting the following error -
"Error in unproxying param 'cpu' of system.intrctrl

Any help or suggestion is appreciated.
Thanks in advance.
