Yes, here is the magic needed for this: 1) make sure you have select UNIX->LINUX 2.x as the OS type in the BIOS (use the HP smartcd to access this) 2) Do not strip out "unused CPU's" like I486_CPU, I586_CPU from your kernel config file. 3) Make sure to either build a GENERIC or SMP kernel with ALL of the devices that are in GENERIC. Do NOT strip out any "unused" devices. I realize this makes the kernel bigger - but what appears to be going on, is that the command to "wake up" the second CPU is being sent too soon after the initial probes for the acpi controller have taken place. At least, that is my theory. Another theory I have is that one of the device probes for an unused device is tickling some piece of hardware on the motherboard that if not otherwise tickled, the second CPU won't wake up. I haven't done further effort to isolate this, but I've seen the problem on the DL320 as well. If you have the time to play with multiple kernel configurations I'm sure you can stumble across what the issue is.
