In our initial posts, we stated that we seemed to be having issues getting the machine to boot with the 4 processors, so to bypass this we disabled ACPI on boot. This allowed us to get past the CPU error and continue to boot. However down the track we noticed things like the ethernet adapater not getting picked up, and the big problem - none of the disks getting recognised. We have since tried a few things, one of which was removing all but one of the CPU's. If we do this, and boot with ACPI enabled, all is totally fine. All disks are found, and I receive no CPU panic error. So it appears to me that by disabling ACPI in an attempt to bypass the QUAD CPU problem, we are causing another issue behind the scenes. The root of the problem now appears to be, that if we have anything over 1 CPU, directly after the kernel is loaded (when booting from the CD), we receive the error message "panic: madt_probe_cpus_handler: CPU ID 38 Too High". The moment a second CPU to the machine....it bombs out.
