[Asterisk-Users] Intel Desktop MotherBoards Unsuitable for DigiumBoards

[Piotr A. Sygula]

Having an issue with shared interrupts with a setup with 3 TDM400P cards,
and dealing with Digium support, I'd like to share with the list the fact
that Digium claims the following:

The following output from "lspci -vb" (shows IRQ from PCI-bus perspective,
rather than the APIC perspective) shows one of your Digium cards sharing
with another device on the system.

0000:01:02.0 Communication controller: Tiger Jet Network Inc. Tiger3XX
Modem/ISDN interface
        Subsystem: Unknown device b119:0003
        Flags: bus master, medium devsel, latency 64, IRQ 5
        I/O ports at de00
        Memory at feafe000 (32-bit, non-prefetchable)
        Capabilities: [40] Power Management version 2

0000:00:1f.3 SMBus: Intel Corp. 82801EB/ER (ICH5/ICH5R) SMBus Controller
(rev 02)
        Subsystem: Dell: Unknown device 019d
        Flags: medium devsel, IRQ 5
        I/O ports at efe0

----

I.e. although APIC is splitting up IRQ's rather nicely, the tech support guy
is saying that it doesn't matter what the APIC layer says.  Would someone
out there "break the tie"?  I'd like an educated opinion/statement on
whether APIC support solves the IRQ sharing issue, or simply masks it.

What this boils down to for me is an elemental issue; either the TDM400P
cards are just flat out crap, and Digium is using any excuse in the book to
keep saps like me hoping that the problem can be fixed by getting another
motherboard, or, APIC shmapic, an IRQ sharing issue is an IRQ sharing issue.

Anyone care to comment???

IRQ.

APIC rocks my world.
