(Shame really, I'd like to replace the real modem on a line on the production server with an IAXmodem process). >> 0: 2087872259 IO-APIC-edge timer >> 7: 0 IO-APIC-edge parport0 >> 8: 1 IO-APIC-edge rtc >> 9: 1 IO-APIC-level acpi >> 14: 18440124 IO-APIC-edge ide0 >> 15: 4456445 IO-APIC-edge libata >> 169: 4878102 IO-APIC-level eth0 >> 177: 2086847525 IO-APIC-level wctdm24xxp >> 185: 2086810653 IO-APIC-level wct4xxp > > > Notice the priorities here... and that your Zaptel cards come *last*, > after eth0, after IDE.

Eg. 8 to 15 have a higher priority than 3 to 7. On the bright side on that machine there is an IRQ -> slot allocation system in the BIOS. On the down side, it appears to do bugger all. (as below) 0: 63 IO-APIC-edge timer 1: 2 IO-APIC-edge i8042 6: 5 IO-APIC-edge floppy 7: 0 IO-APIC-edge parport0 8: 1 IO-APIC-edge rtc 9: 0 IO-APIC-fasteoi acpi 12: 3 IO-APIC-edge i8042 14: 4744 IO-APIC-edge ide0 15: 11412 IO-APIC-edge ide1 17: 428 IO-APIC-fasteoi eth0 19: 40266 IO-APIC-fasteoi ehci_hcd:usb1, uhci_hcd:usb2, uhci_hcd:usb3, uhci_hcd:usb4, uhci_hcd:usb5 20: 0 IO-APIC-fasteoi VIA8237 21: 1284151 IO-APIC-fasteoi wctdm I've also noticed that on the production server, the card not only has the lowest priority but is now sharing an IRQ (probably happened last time I saw fit to shut the machine down). 0: 2931864860 XT-PIC timer 1: 1659 XT-PIC i8042 2: 0 XT-PIC cascade 3: 270 XT-PIC uhci_hcd:usb3 4: 3231957 XT-PIC serial 5: 0 XT-PIC uhci_hcd:usb4 6: 13146224 XT-PIC dpti0 7: 475736174 XT-PIC eth0, eth1 8: 4 XT-PIC rtc 10: 0 XT-PIC uhci_hcd:usb2, uhci_hcd:usb5 11: 2931432215 XT-PIC ehci_hcd:usb1, wctdm 14: 759 XT-PIC ide0 Guess I'll try disabling the USB controllers and moving cards round again. _______________________________________________ --Bandwidth and Colocation Provided by http://www.api-digital.com-- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
