[asterisk-users] Terrible dahdi_test results

[Mike Leddy]

Hello, I am trying to get a Wildcard TE110P to work in a relatively
modern HP Proliant DL385p Gen8 server. Being a potent 12 core Opteron
server I expected no problems.

Much to my dismay the dahdi_test results are constantly terrible:

# dahdi_test

Cummulative Accuracy (not per pass): 89.089

Trying to use the card results in constant 'HDLC Bad FCS' and
consequent 'HDLC Abort'.

As far as I can tell everything should be fine. The card has its 
own IO-APIC interrupt (28). I tried setting its smp_affinity to 
one cpu, changed the pci card latency... to no avail, always
the same terrible dahdi_test results.

Some info:

Should I just give up on using the card in this server ? 
Is there anything else I can try ? 
What other information may be relevant ?

Many thanks in advance.
