Intel® Desktop Board DZ77SL-50K PCI & PCI E Use Same IRQ

Hi,

I have purchased "Intel® Desktop Board DZ77SL-50K" on which i have connected One PCI Openvox 8 Port Analog Card and one PCI-E Openvox 8 Port Analog Card on my Asterisk Elastix Version # 1.8 Lunix Server. For some reason when make & receive calls, i get lots of noise disturbance. When I check Cat / proc / interrupts from root. I found

CPU0 CPU1 CPU2 CPU3

90 : 46010866 10326340 0 0 IO-APIC-LEVEL OPVXA1200, OPVXA24xx

I upgraded Dahdi drivers & card Drivers. To resolve temporary, I have to connect extra available Openvox 8 Port Card on another PCI Card, now it shows different IRQ

CPU0 CPU1 CPU2 CPU3

90 : 46010866 10326340 0 0 IO-APIC-LEVEL OPVXA1200 (PCI), OPVXA24xx (PCI-E)

169 : 66010866 45426340 0 0 IO-APIC-LEVEL OPVXA1200.(PCI)

 

Then I only use PCI-E from First 1 Line and PCI from Second to continue our system running, I spoked to many asterisk or linux experts, they said its problem with Motherboard issue. They will well support you.

Im looking for a solution configuration or setting either from Intel Motherboard Bios or OS Linux setting Configuration to have PCI or PCI-E Card own seperate IRQs for each card.

Please help me, Thanks in Advance

Sam

Hello ITsupport5589,

It is important to tell you that Intel has not tested and validated Intel® boards on any Linux versions; we know that other customers have successfully installed it.

 

Regarding IRQs, there are some links that shows how to change IRQ manually on Windows 7 or 8.1
