[asterisk-users] Re: Dell PowerEdge 2950 Sharing NIC IRQ with Digium Card

[Matt]

Ok.. I have to admit I'm a little confused now.   I looked at some of my
machines again that work flawlessly and they have things like this (although
in BIOS it shows no sharing of IRQs)

          CPU0
  0: 1448934642    IO-APIC-edge  timer
  1:        228    IO-APIC-edge  i8042
  8:          1    IO-APIC-edge  rtc
  9:          1   IO-APIC-level  acpi
201:   83745144   IO-APIC-level  eth0
217:    7686337   IO-APIC-level  libata
233: 1446873007   IO-APIC-level  wctdm24xxp


AND

           CPU0       CPU1
  0:  362899607  362907717    IO-APIC-edge  timer
  1:          0         25    IO-APIC-edge  keyboard
  2:          0          0          XT-PIC  cascade
  8:          0          1    IO-APIC-edge  rtc
 14:          0          2    IO-APIC-edge  ide0
 16:          0          0   IO-APIC-level  usb-uhci
 18:          0          0   IO-APIC-level  usb-uhci
 19:          0          0   IO-APIC-level  usb-uhci
 23:          0         24   IO-APIC-level  ehci-hcd
 38:    7310507   39341308   IO-APIC-level  megaraid
 48: 2165109942        255   IO-APIC-level  eth0
 77:  996436331 1968405724   IO-APIC-level  wcte11xp
 82: 1930286687 1032956864   IO-APIC-level  wct4xxp

No problems on those systems, yet it looks like they are doing APIC IRQ
sharing (though BIOS shows otherwise).

Then I have this sytem that Digium said is doing too much sharing:
           CPU0
  0:   76478196    IO-APIC-edge  timer
  1:         79    IO-APIC-edge  i8042
  2:          0          XT-PIC  cascade
  8:          1    IO-APIC-edge  rtc
 12:         93    IO-APIC-edge  i8042
 14:         23    IO-APIC-edge  ide0
121:     183199   IO-APIC-level  uhci_hcd:usb2, eth0
137:          0   IO-APIC-level  uhci_hcd:usb3
153:          0   IO-APIC-level  ehci_hcd:usb1
161:      84182   IO-APIC-level  ips
169:   76431251   IO-APIC-level  wctdm24xxp
NMI:          0
