Hi, I have an IBM xSeries server... and the digium card is sharing IRQ with USB and giving me crackling audio.>>> cat /proc/interrupts >>> >>> It brings up these results: >>> 0: 10566547 IO-APIC-edge timer >>> 1: 9 IO-APIC-edge i8042 >>> 2: 0 XT-PIC cascade >>> 8: 1 IO-APIC-edge rtc >>> 12: 93 IO-APIC-edge i8042 >>> 14: 23 IO-APIC-edge ide0 >>> 121: 481478 IO-APIC-level uhci_hcd:usb2, eth0 >>> 137: 0 IO-APIC-level uhci_hcd:usb3 >>> 153: 0 IO-APIC-level ehci_hcd:usb1 >>> 161: 28479 IO-APIC-level ips >>> 169: 10526429 IO-APIC-level wctdm24xxpIBM is saying that I can not disable the USB ports!!!!! Can anyone offer any insight.. either as to how to disable the USB ports, or how to make this work on an IBM xSeries?
compile kernel without usb support or unload usb modules turby ps your tdm card don't share the irq, your network card share the irq... -----Original Message----- From: asterisk-users-bounces@lists.digium.com [mailto:asterisk-users-bounces@lists.digium.com] On Behalf Of Matt Sent: Thursday, December 14, 2006 5:13 PM To: Asterisk Users Mailing List - Non-Commercial Discussion Subject: [asterisk-users] IBM Server / USB Ports Hi, I have an IBM xSeries server... and the digium card is sharing IRQ with USB and giving me crackling audio.>>> cat /proc/interrupts >>> >>> It brings up these results: >>> 0: 10566547 IO-APIC-edge timer >>> 1: 9 IO-APIC-edge i8042 >>> 2: 0 XT-PIC cascade >>> 8: 1 IO-APIC-edge rtc >>> 12: 93 IO-APIC-edge i8042 >>> 14: 23 IO-APIC-edge ide0 >>> 121: 481478 IO-APIC-level uhci_hcd:usb2, eth0 >>> 137: 0 IO-APIC-level uhci_hcd:usb3 >>> 153: 0 IO-APIC-level ehci_hcd:usb1 >>> 161: 28479 IO-APIC-level ips >>> 169: 10526429 IO-APIC-level wctdm24xxpIBM is saying that I can not disable the USB ports!!!!!

I guess you'd suddenly get interrupts here. I bet all the interrupts on 121 are from the network controller.> >>>161: 28479 IO-APIC-level ips > >>>169: 10526429 IO-APIC-level wctdm24xxp > > IBM is saying that I can not disable the USB ports!!!!!
