IRQ routing conflicts
Hi all, I'm having a serious problem with SuSE 9.0. The system seems to run well, but sometimes it just stops. Further If you use USB or ethernet witha very heavy load it also just stops. Nothing in /var/log/messages it just hangs. Looking with dmesg it see a lot of IRQ routing conflicts, and indeed they are related to the USB, ethernet and IDE controller. From /proc/interrupts it becomes clear that the external IDE card and One of the USB controller share interrupt 4 and At interrupt 12 there is the ethernet controller and another USB controller. Anybody knows how to solve this? System: Asus A7V600-X onboard IDE + SATA onboard ethernet onboard 4xUSB 2.0 external SIL680 raid controller externat S3 SAVAGE AGP video card Thanks in advance.

Anybody knows how to solve this? I had similar problems in the past and I got around it by setting the BIOS to arrange the interrupts. I even individually set the IRQ number for each PCI slot so nothing was sharing an interrupt. The boards that gave me the most trouble were all Asus boards. With my own experience and your post, I am begining to dislike Asus boards. with one of my Asus boards, the certain slots share interrupts and there is no way around it so I had to keep swapping cards around until I found a combination that worked.
