D110P - PRI span 1/0: Provisioned, Down, Active

*Describe the problem in details(logs, errors)
D110P - PRI span 1/0: Provisioned, Down, Active

Unable to get the span UP, it goes from green to yellow alarms with errors like this.
[Oct 15 08:13:49] NOTICE[6276]: chan_dahdi.c:13520 pri_dchannel: PRI got event: No more alarm (5) on Primary D-channel of span 1

[Oct 15 08:14:04] NOTICE[6276]: chan_dahdi.c:13520 pri_dchannel: PRI got event: HDLC Bad FCS ( on Primary D-channel of span 1

In intense debug mode I only see outgoing frames.

hi,

you can disable the crc4 in your side and telcom side then restart dahdi and asterisk to try, if still have problem, you can contact me via skype, i will help you to check it remotely

I've already tried that it has the same effect. Any other ideas?

hi,

you can add the following parameters at the kernel line in grub.conf then reboot the system to try
example:
title Elastix (2.6.18-238.12.1.el5)
root (hd0,0)
kernel /vmlinuz-2.6.18-238.12.1.el5 ro root=/dev/VolGroup00/LogVol00 acpi=off noapic
initrd /initrd-2.6.18-238.12.1.el5.img

I'm afraid that on 64bit SMP kernel apic has to stay on without it the system freezes with softlockups and is unworkable. Anyway I've put the card on it's own interrupt and enabled SMP IRQ Affinity to be processed on 2nd cpu. This is a result of dahdi_test
