Any suggestion on this will be highly appreciated. I'm running linux 2.4.20 and rtai 24.1.11. My linux kernel module needs to use IRQ 9 10 11 for AGP graphic card, sound card and PCI-Dio24 IO card. These irqs are also shared by USB controllers. My module hangs when it tries to request one of the above irqs that is used by USB keyboard. I am using DELL machine, and its bios cannot reserve irq's. I also tried to set boot paramter "pci=irqmask=0xf1ef" to reserve irqs 9 10 11 4 for my driver, and it hasn't had any effect - those irqs are still used by usb controllers on initialization. How to solve this irq confliction problem? Thanks in advance, jing __________________________________ Do you Yahoo!? New Yahoo! Photos - easier uploading and sharing. http://photos.yahoo.com/
