[Asterisk-Users] te110p and interrupts

[Anton Krall]

Guys. I have an issue with a te110p card and also some tdm04b cards on the
same system:

Zttest returns this for the tdm04b cards:

Opened pseudo zap interface, measuring accuracy...

Im getting problems receiving faxes which can be caused by this.

As you can see, the cards are not sharing IRQs as far as I cant tell

           CPU0       CPU1
  0:   17697848   17714488    IO-APIC-edge  timer
  7:          2          2    IO-APIC-edge  parport0
  8:          1          0    IO-APIC-edge  rtc
  9:          0          1   IO-APIC-level  acpi
 14:     103455     112606    IO-APIC-edge  ide0
 15:          0          0    IO-APIC-edge  libata
169:          0          0   IO-APIC-level  uhci_hcd:usb2
185:    2793868         12   IO-APIC-level  eth0
201:          0          0   IO-APIC-level  ehci_hcd:usb1
209:          0          0   IO-APIC-level  uhci_hcd:usb3
217:   19672684   15531101   IO-APIC-level  wcte11xp
225:   17824822   17371238   IO-APIC-level  wctdm
233:   15323598   19896224   IO-APIC-level  wctdm

So, can anybody point me in the right direction in order to debug the
problem with zttest and quality of sound?
How can I change prioritiess for the cards or maybe adjust or see if they
get their right number of interrupts, etc?

Thx for the help guys!
