Question Changing IRQs


I'm trying to get a X100P card to work.

#modprobe zaptel
#modprobe wcfxo

#ztcfg -vv:
------------------------------------------------------------------------
Zaptel Version: 1.4.7
Echo Canceller: MG2
Configuration
======================
Channel map:

Channel 01: FXS Kewlstart (Default) (Slaves: 01)

1 channels to configure.

ZT_CHANCONFIG failed on channel 1: No such device or address (6)
------------------------------------------------------------------------

#dmesg:

------------------------------------------------------------------------

I think the problem is that the IRQ 19 is shared between the "Intel Corporation 82801EB/ER (ICH5/ICH5R) USB2 EHCI Controller" and the "Motorola Wildcard X100P". So, how can I change the IRQ assigned to the X100P card?

Thank you for your help.

Is this a PCI card?
If so move it to a different slot on the motherboard.

Hello Brian1, and thank you for your answer.

I have tried it, but it shows the same problem.

Do you know any other solution?

Only moving pci cards around to different slots is the only thing I know to try that is easy. Might try this. On boot hit the e key to edit the boot line. Select the boot kernel line and add ' no irqpool ' to the end and press the b key to boot the kernel with that option.
