Hmm.. I'm very surprised this works.
The correct solution is to do
something like:
if test_sys.iobridge:
test_sys.iobridge.ranges.append(AddrRange(mem_size))
else:
#instaniate a bridge
A third option may be to just all the x86 bridge
something else ioapic_bridge and have two bridges (one handling each
range).

Hey guys,
Just ran into this myself. The IO bridge is being instantiated twice,
once in FSConfig.py and again in the fs.py file. I was able to fix it
for X86_FS simply by adding an if clause in the fs.py file (line 166)
where it is instantiated the second time:
if not test_sys.iobridge:
test_sys.iobridge = Bridge(delay='50ns', nack_delay='4ns',
ranges = [AddrRange(mem_size)])
test_sys.iobridge.slave =
test_sys.iobus.port
test_sys.iobridge.master = test_sys.membus.port
I'm not sure if this would upset other architectures though.

I got this error too just now. It looks like it may
have something to do
with the port/bus/bridge changes that have gone
in recently.

I just updated to the latest version of gem5 and noticed the merge of
