Also, make sure you have the max number of processors in the SMP section of the kernel config set appropriately. Also, if you use /proc, then 'cat /proc/cpuinfo' or 'cat '/proc/interrupts' and use that to see what's actually enabled. Check 'dmesg' as well and see how many processors were found and brought up. I had trouble a year and a half ago with Hyperthreading on my Intel 531 not getting enabled. ACPI wasn't enabled and that was the problem. It's required for SMP to work fully, apparently. Of course, in the process, I found out that on this system I couldn't use a PS/2 keyboard since ACPI was causing an interrupt shuffle during the kernel boot and the keyboard lost the lottery. So, a USB keyboard fixed that problem. Hope some of that helps. -- Statux <[EMAIL PROTECTED]>
