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

    itsupport5589

      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
