[Asterisk-Users] Hardware

I have a system with VIA chipsets with one T400P (3FXS,1FXO) and 2 E100P (for 
testing with a cross over cable between them), and the only problem I have is 
when I do something like:

exten => 5700,1,Dial(Zap/g3/5701)
exten => 5701,1,Dial(Zap/g3/5702)
exten => 5702,1,Dial(Zap/g3/5703)
exten => 5703,1,Dial(Zap/g3/5704)
exten => 5704,1,Dial(Zap/g3/5705)
exten => 5705,1,Dial(Zap/g3/5706)
exten => 5706,1,Dial(Zap/g3/5707)
exten => 5707,1,Dial(Zap/g3/5708)
exten => 5708,1,Dial(Zap/g3/5709)
exten => 5709,1,Dial(Zap/g3/5710)
exten => 5710,1,Dial(Zap/g3/5711)
exten => 5711,1,Dial(Zap/g3/5712)
exten => 5712,1,Dial(Zap/g3/5713)
exten => 5713,1,Dial(Zap/g3/5714)
exten => 5714,1,Dial(Zap/g3/5715)
exten => 5715,1,Dial(Zap/g3/5716)
exten => 5716,1,Dial(Zap/g3/5717)
exten => 5717,1,Dial(Zap/g3/5718)
exten => 5718,1,Dial(Zap/g3/5719)
exten => 5719,1,Dial(Zap/g3/5720)
exten => 5720,1,Dial(Zap/g3/5721)
exten => 5721,1,Dial(Zap/g3/5722)
exten => 5722,1,Dial(Zap/g3/5723)
exten => 5723,1,Dial(Zap/g3/5724)
exten => 5724,1,Dial(Zap/g3/5725)
exten => 5725,1,Dial(Zap/g3/5726)
exten => 5726,1,Dial(Zap/g3/5727)
exten => 5727,1,Dial(Zap/g3/5728)
exten => 5728,1,Dial(Zap/g3/5729)
exten => 5729,1,Dial(Zap/g3/5730)
exten => 5730,1,Dial(Zap/g2)

So I can call 5700 and have all E1 30 channels active I get echo.
However, cpu load is very low, I see no missed interrupts:

[root at macp1 ~]# cat /proc/interrupts
           CPU0
  0:   40705272    IO-APIC-edge  timer
  1:      32140    IO-APIC-edge  i8042

217:    1894342   IO-APIC-level  eth0

NMI:          0
LOC:   40707037
ERR:          0
MIS:          0

If I call 5728, everything is fine.

As you can see, IO-APIC-level takes care of giving each PCI device a 
completely separate interrupt.

This is a ECS KT600-A, with an Athlon XP 2600+ FSB 333 processor, 1GB (2x 
512MB) DDR 333 memory, 2 SATA HD's and a nVidia video card, onboard 10/100 
ethernet.
