Hi
I have come across a problem, with my tdp410 and soekris board
(basically pc on a chip amd geode cpu).
I am using the box as a firewall/asterisk box. The problem occurs when I
drop ppp and I get dead loop dectiotn going, I seem to lose interrupts
and get lots of messages in syslog from wctdm24xx saying missed
interrupt increasing latency
its out lined here
(http://forums.digium.com/viewtopic.php?p=126997&highlight=&sid=9de59f41f1a93ee8701b28fdd0cf6073)
Seems like the driver (and this is in zaptel & dadhi code), increases
latency by +1 until 30. and then the card seems to not work. In my case
I have seen latency increase from 8m (I have this as a starting point in
the module load) up to 17ms usually around here the fxs and fxo ports
stop working ..... I have to unload and then reload the module. bummer.
I can think of a couple of solutions
1) build some intelligence to bring down the number when things are okay
2) build logic to say if a number is provided on module load to fix it
to that
3) add a sysfs (/proc) interface to allow changing this value on the fly
I could also try and solve my problem with the dead loop detection
cat /proc/interrupts
CPU0
0: 23809265 XT-PIC-XT timer
1: 0 XT-PIC-XT i8042
2: 0 XT-PIC-XT cascade
4: 255 XT-PIC-XT serial
5: 459544 XT-PIC-XT eth1
8: 0 XT-PIC-XT rtc0
10: 95177163 XT-PIC-XT wctdm24xxp0
11: 28938443 XT-PIC-XT eth0
12: 28938632 XT-PIC-XT eth3
14: 3624228 XT-PIC-XT ide0
15: 1 XT-PIC-XT ehci_hcd:usb1, ohci_hcd:usb2
NMI: 0 Non-maskable interrupts
LOC: 0 Local timer interrupts
TRM: 0 Thermal event interrupts
SPU: 0 Spurious interrupts
ERR: 0
MIS: 0
as you can see with the interrupts the wctdm24xxp0 is above eth0 (local
lan) and eth3 (my adsl)
eth1 is wireless and not heavily used
So any one had this problems, any other possible solution to this ?
How to engage digium to providing a fix for this ?

If that is the case, then that is your problem as Asterisk does not tolerate the lose of DNS resolution very well. Lyle Giese LCR Computer Services, Inc.
