Hi Mark, > What does the failure look like? Silent hang or any messages or what? With the -smp 4, the kernel started, but I got this: Starting kernel ... Error: unrecognized/unsupported processor variant (0x2033dd00). The kernel works if the smp option is not used (set to 1, I think). I also noticed the boot process was extremely slow.
