Thanks again Russ,
I did as you described:

I suspect it may not be good enough yet for production but a
step in the right direction :-)
Hi Russ,
I rebooted the machine loading dahdi_dummy in /etc/modules before
the /etc/init.d/dahdi.
Now dahdi_test shows a nearly perfect score:

Opened pseudo dahdi interface, measuring accuracy...

Hi Russ,
Sorry I didn't send that... Here's a few runs:

Thanks for the suggestion Gareth,
The span line I'm using is:
span=1,1,0,ccs,hdb3,crc4
Its the same as used with the TE12xP that is normally used on this
E1 line in production which is extremely stable.
I did as you suggested using:
span=1,0,0,ccs,hdb3,crc4

Unless you're using a relatively old version of dahdi, there's no
separate module called dahdi_dummy. It is an alias to the main dahdi
I remembered I have an older box with a Wildcard TE12xP that
uses the wcte12xp module with a newer 3.9.11 kernel that works
perfectly.
I setup the problematic machine with the same kernel in the hope
that this might be relevant. Unfortunately the same situation
persists.

Hi Eric,
I plugged an E1 into the card and it doesn't make any difference.
Check to see if the card is interrupting 1000 times per second with
something like:
cat /proc/interrupts | grep wc sleep 1 cat /proc/interrupts |
Thanks Russ,
I blacklisted wcopenpci, and i noticed an improvement:

With this in mind I might start looking around the system for things which

Just a quick reply for now.
No virtualization, but yes I am running a tickless kernel:

Standard for debian kernels. I booted with nohz=off and the behaviour
changed. Unfortunately for the worse:
