Segmentation problem, modprobe, Asterisk
 

I am having a problem with my linux box. It is a Slackware 9.1 machine. It had been working fine for about half a year and then last week I installed a generic version of the Wildcard X100P card which uses the zaptel and wcfxo drivers. I had it working for awhile and then weird things started happening. I don't know that it is directly related to using this card, but all the problems started around that time.

The problems:
-If I use hotplug it does not allow me to login. The login prompt comes up and I type my password in but it just comes up with another login prompt. Also, sometimes it logs me in and the overwrites the screen with the prompt again.
-When I am able to login(turning off hotplug), I do a modprobe 8139too for my ethernet card, then a modprobe zaptel, then a modprobe wcfxo. Once I have done this I am not able to run any programs, they all give me a Segmentation Fault.
-I have already re-imaged and re-installed the machine and it is still giving me errors.

Please help if you have any ideas. Tell me if you need to post any more information. Thanks.

maybe conflicting interrupts. be sure they all have their own. look at /proc/interrupts. you may also try to use another placement in your pci-slots to solve this (if it's irq-related).

really sounds weird. i can't imagine 'bout a interaction between usb and your login with your newly installed card?

Thanks for the post...I checked the interrupts and I do believe that it is a problem with them. Everything works fine until I load the wcfxo module which uses interrupt 11. Below is my /var/log/messages, /proc/interrupts, and lspci after I have loaded the modules. I tried to load change the options in modules.conf for an irq=9 for the wcfxo module but it says it does not let me load it with 9 as the interrupt. Any ideas how I can fix these? Thanks.

you can try putting the cards in other pci slots. this way you'll have to open the box and fiddle around till you got it.
maybe you can disable pnp in your bios and asign irq's to cards manualy. some bios's here are really $!%?!#!!.
to be sure it's the irq-settings: you can disable usb in your bios or at loading the kernel(?..look at /usr/src/your_kernel/Documentation/kernel-parameters.txt). then see if it's working as it should.

You can try to freshen up modprobe and the kernel by re-compiling them. It could be a module problem conflicting with your system. How new is Wildcard X100P. If its new and your system is only having the problem then you can upgrade the BIOS or get a device that will replace Wildcard X100P. You can take out the Soundblaster LIVE and to see if your Wildcard X100P works. The Soundblaster LIVE is known to have problems with your chipset.
