Try switching to a Sangoma card. You wont have anymore IRQ issues once you abandon Digium hardware.

I'm currently trying everything again anyway, but i doubt it will work if nothing worked the first time. Anyone would know of issues with XEN or SMP (or both) kernel? Do dual core AMD64 processors have issues? François. Michael L. Young wrote: François, I too had a similar problem and found the information on this page helpful: http://www.voip-info.org/wiki/view/Asterisk+PCI+bus+Troubleshooting What ended up working for me was changing the UDMA to mode 2 for the hard drive. Once I did that, this card has worked perfectly for me. Michael L.

Any idea about this? Is it possible to force the timer to ztdummy (RTC timer) when you have a zap card plugged in? It's the only thing i could try to make it work. Thanks, François.
