The problem that I am having is that when I turn on the second processor
( via the options in the kernel config file) I get all kinds of timeouts
with the network cards. According to the archives, people have stated
that it is a poorly implemented interrupt/apic setup on the Motherboard.
The machine is a Gateway NS-7000 with 2 300 mhz Pentium II processors.
The motherboard in this machine appears to be the ALR revolution 2x.
Is there any way I can fix this problem or am I doomed to running it in
single cpu mode?
