Hi,

I am trying to simulate O3 CPU in FS mode, without ruby. However, the
moment I specify more than 1 cores, i get the same error as mentioned in
this thread. Any idea about how this could be resolved ?

**** REAL SIMULATION ****
info: Entering event queue @ 0.  Starting simulation...
warn: Don't know what interrupt to clear for console.
warn: instruction 'fxsave' unimplemented
warn: instruction 'wbinvd' unimplemented
warn: instruction 'wbinvd' unimplemented
hack: Assuming logical destinations are 1 << id.
panic: Unable to find destination for addr 0xa000000000001000
 @ cycle 174196088592
[findPort:build/X86/mem/bus.cc, line 325]
Memory Usage: 303284 KBytes


I have booted with 2GB of memory. Any thoughts ?

Thanks for your help.

Regards,
Ankita
