It should halt, but the CPU may wake up again and continue executing if an interrupt arrives. All should be masked, but you never know.. > If so, shall we move the loop into hlt() itself? I don't think so. hlt() is just a C wrapper around the instruction. Eventually I imagine building a panic room into die() so that recovery can be made via console on fatal errors. Ideally with some kind of stub for debugging stage0 and definately one for initram. > Merge hlt() into cpu.h where it belongs.
