[Asterisk-Users] IRQ Problems

Hello
I just installed a TE110P in a Dell Poweredge 750 (rackmount), which
is connected via crossover T1 cable to a adit 600.  Anyway, I've
encountered an array of errors, which I believe I have narrowed down
to the 22 IRQ misses I encounter on zttool. I've noticed that the
te110p and the usb device share an IRQ. Could that be the source of my
woes? Would disabling the usb device in the bios solve my problems or
could it be my configuration?

Tom,

For this errror, you need to type the following on the Adit.

The sharing of an IRQ is indeed a problem

Read this tutorial to know exactly what to do:

[Asterisk-Users] IRQ Problems

The problem is that both adit600 and Asterisk box are configured as 
clock slaves (pri_cpe).
Change pri_cpe to pri_net in your zapata.conf, and your asterisk box 
would be the clock source.
It should work. Good Luck.

Argentilinux.

[Asterisk-Users] IRQ Problems

I put a TE110P in a 750 and got lots of scratchy audio and hdlc errors,
missed interrupts I presume.  Anyway, I found I had to do the following in
order to get good audio quality and successful spandsp:

    Disable Hyperthreading
    Put TDM card in bottom slot (The 3.3v slot).  If you specify SATA raid
or SCSI the controller will occupy this slot and YMMV, during testing I had
significantly more audio issues with the TE110P in the top slot.
    Compile SMP kernel to get APIC interrupt support (I have a DRAC card in
this server that takes 3 interrupts, 2 of which it shared with the TDM card
with a uniprocessor kernel).
    Runlevel 3 (ie no X-windows)
    You cannot unload the zaptel driver once loaded as it hangs the machine.
We do a shutdown without unloading the driver and power cycle using the DRAC
card)
    Dell DRAC card uses VNC for remote console access (even in runlevel 3)
which is pretty useless.  Enable telnet on the DRAC card for console access.
