This change causes my 2-cpu, x86-64 VirtualBox VM to hang hard immediately on boot, regardless of how I build the kernel. If I build the kernel with DEBUG, it hangs immediately after printing "kernel text is mapped with 6 large pages and 442 normal pages". In fact, it hangs so hard that it makes VirtualBox throw a fatal error when I try to reset the VM. I understand this change is _not_ causing trouble for some others, but it sure does for me. Can we back it out temporarily, and what can I offer by way of help in debugging it? Thor
