Re: [SLE] irqbalance question on openSuSE 10.1

On /etc/init.d/irq_balancer LINE 41 there is the following line

witch explicitly states that the $PHYS variable has to be greater
then one.

Actually, it says "PHYS>0" _OR_ " "PHYS==0 and PROC>1". The latter is
the case on my 4-way box, so irqbalance is active.

This means that there has to be two physical processors, and
the daemon will not load if the computer has either a Hyper-Threading
or Dual-Core CPU.

I don't know what /proc/cpuinfo looks like for a dual-core, but a
dual-core machine certainly has two physical processors, even they're
not on different carriers.

Hyperhreading is different - only one processor that pretends to do more
things at the same time :-)

Post your /proc/cpuinfo.
