Thought I'd try here as I'm getting no help in Ubuntuforum.org...


I have a Proliant 5500 which is currently running three Xeon 550MHz
processors, I've installed Ubuntu Server 7.04 and it has auto detected
my setup and installed the generic i686 kernel (2.6.20-16 #2 SMP)
which as the name suggests is supposed to be SMP aware.


Problem is when I run 'cat /proc/cpuinfo' I only get details for one
processor, similarly in /sys/devices/system/cpu I only get an entry
for cpu0 when I should see cpu0, cpu1 and cpu2.


Anyone here shed some light on this?

I came across this problem before, when I went from one to two
processors and unfortunately the option is already set to Linux.
Everything worked fine running SME Server 6.01 which is based on
RedHat 7.2, but for some reason Ubuntu is returning an error of "SMP
motherboard not detected" and reverting to UP mode during boot. Which
is odd when you think RedHat 7.2 is a very old version and that worked
fine...
