Hi all, I ran X86 in full system with a SPLASH benchmark ocean_cp successfully. However, when I tried to run the same benchmark with X86 full system+ Ruby. I got this: "MP-BIOS bug: 8254 timer not connected to IO-APIC". And then the system stalled. I wonder how to solve this problem. Thanks!

Actually, it also happens to multiple cores without ruby. Does anyone know the solution? Thanks!

Hi Nilay, Sorry that I forgot to ask a question. I have tried to use the default clock rate for cpus (2GHz) and it boots successfully. I wonder if it is possible to have cpus with 5GHz clock rates. If so, what's the correct way to make it work. Is there a limit for the maximum clock rate in X86 FS and what it is? Thanks a lot!
