asterisk users - Jan 2012 - ISDN E1, after electrical disconnected is not becoming UP, IRQ misses: 1

Dear All;

I am afraid from IRQ misses: 1

The ISDN E1 was working fine on the machine, the electrical disconnected and
then the Red Allarm. I checked the dahdi and I found that I have to reinstall
dahdi again and I did. But still not becoming UP.

The output of the cat /proc/dahdi/1 is following (I am afraid from the IRQ
misses: 1, so if it is a problem what is the solution)?

[root at CC asterisk]# cat /proc/dahdi/1
Span 1: TE2/0/1 "T2XXP (PCI) Card 0 Span 1" (MASTER) HDB3/CCS/CRC4 RED

If it's just one IRQ miss, I don't think that by itself is anything to
worry about, although I would make sure you don't have a frame buffer,
slow serial console, etc.. configured on this system.

I am not sure why you would have to reinstall DAHDI after
disconnecting the electricity unless the disk was corrupted because
it was just installed without syncing to the disk.

I would make sure that that you can put the span in loopback and run
patlooptest: ie.

 /usr/src/dahdi-tools# dahdi_maint -s 1 --loopback localhost
 /usr/src/dahdi-tools# ./patlooptest /dev/dahdi/1 -t 10
 Using Timeout of 10 Seconds
 Going for it...
 Timeout achieved Ending Program
 Test ran 33 loops of 2039 bytes/loop with 0 errors
 /usr/src/dahdi-tools# dahdi_maint -s 1 --loopback off
 Span 1: loopback OFF

If that works you will most likely need to investigate with your
provider. They may have to reset things on their end.
