Subject: Dodgy interrupts To: 'FreeBSD Hardware mailing list' Message-id: <59063B5B4D98D311BC0D0001FA7E45220FD14E@l04.research.kpn.com> MIME-version: 1.0 X-Mailer: Internet Mail Service (5.5.2650.21) Content-type: text/plain; charset="iso-8859-1" Sender: owner-freebsd-hardware@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.org Dear FreeBSD-hardware, I seem to disagree with my ethernet card about interrupts. It could be that the card is just plain old broken, but I don't want to buy a new one if there's a chance it's going to do the exact same thing. Set-up: ABit BX/PX motherboard, AMD k6-233 4 PCI slots: diamond Viper 550 (or 330... geez, why haven't I written this down) 2x nrc810 ehternet card (err. lnc1, I don't know the brand) The ethernet card shares its interrupt (irq 14) with the USB controller. I don't actually use the USB controller, so if someone can suggest how to switch it off, please do. I used to have my video board in the PCI slot that my ethernet conroller is in now, but my system would randomly crash and freeze. Diamond's readme told me to move the video board into an unshared interrupt slot, and it worked. Later I got the ethernet card, which worked for a while, and now is broken too. I'm not a heavy user of the ethernet board, since for a long time I had no machine to ethernet with. Now I NFS mount over TCP and that works, albeit slow. UDP traffic is lost. I get "impossible packet length" and "NFS server not responding", but things sort itself out after a few seconds. Windows can't even use the card, but tells me it's "working properly". Go FreeBSD! My questions: Does the value of the irq matter? I hear lower irq's have higher priority. Is a higer priority necessary for a modern ethernet board? Are there problems with shared irq's on PCI boards? Abit in particular? How come I only have problems with PCI ethernet boards, and all the ISA ones I've ever used worked *always*?
