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 ? Alex
