Hi Giovanni, Are you suggesting to enable or disable the IO APIC setting?
I have been running with IO APIC enabled, and I experience the lock-up problem when more than one CPU is enabled, but not when only one is enabled. As you mention, in VirtualBox version 3.0.2 the IO APIC is enabled by default. In response to your message I tried to disable it. But apparently VirtualBox disallows this. Every time I uncheck the box to disable it, the next time I enter that page the box is checked again. According to the documentation, the IO APIC mus be enabled for 64-bit guests or if more than one CPU is enabled. Apparently the software disallows what it considers to be an invalid configuration. Are you saying that your system used to also lock up occasionally and after you made a change now it is not?
