asterisk users - Jan 2006 - TE411P in a HP DL360 - which BIOS settings work?

Greetings,

For a couple of months, we ran a pilot implementation of Asterisk with 
a TE110P on a HP NetServer LP1000r with perfect audio quality and no 
echo on a T1.

Encouraged by this, we purchased two identical HP DL360 servers with 
TE411P cards for a production installation of Asterisk. We reproduced, 
as close as we were able, the configuration that we had on the pilot 
server. This is what we have now on our DL360s (twin 3.4GHz Xeons and 
4GB of memory):

	- Latest stable build of asterisk, zaptel and libpri (1.2.1)
	- APIC turned off
	- Hyperthreading disabled
	- USB disabled
	- Physical and virtual COM ports disabled
	- TE411P on its own on IRQ4

We have also tried APIC and hyperthreading on with no perceptible 
difference.

We have problems with echo, scratchy audio, pops, clicks and drop outs 
that we cannot seem to make go away. We have had kernel panics when 
downing network interface cards, and, on one of the servers, kernel 
messages that say "Disabling IRQ #11" when we modprobe wct4xxp.

Is there anyone out there who has gotten this combination of hardware 
working satisfactorily and would like to share their BIOS and IRQ 
settings and anything else they did to get it working? I know it must 
work - the DL360 is one of the two supported servers for ABE.

We have emailed Digium support and are waiting for a response from 
them, but I wanted to poll the list and see if there was anyone with a 
working implementation out there.

Regards,
