I am running Asterisk 18.104.22.168, dahdi 2.4.0 and libpri 22.214.171.124 on an
HP ML110 G6 using Ubuntu Linux 10.04 LTS.
I have two Digium TE121 single T1 port cards and a Digium AEX800
8-port FXS card. All PCI Express cards.
Co-workers are hearing hissing sounds on some calls, and I am getting
IRQ errors when running “dahdi show status”.
I see that sharing IRQs for Digium cards isn’t recommended, so I’m
trying to set it so each card gets its own. From the few web sites
I’ve read so far, including Digium’s FAQ site, I’ve added ACPI and
verified that the BIOS does not give me the ability to manually set
the IRQ. I’ve even taken one of the TE121’s out of the server (it
isn’t being used anyways). Everything I’ve done so far has not fixed
it. All the cards (as well as USB1) all use IRQ 16.
The other option given was to use setpci, but I am unfamiliar with
that command. I did what I could to try and find the setting (based
on what the man page on Ubuntu’s web site) where I could see the value
16, but not getting anywhere.
I know that this is more of an Asterisk forum than Digium. If I need
to put in a case at Digium I will, but wanted to see if there were any
suggestions here before I pursued that.
Any help would be appreciated.
