dhcp & spurious interrupt

campbellop · 06-20-2002, 03:20 AM

I've got dhcpd up and running, but when a client machine starts its network script, I get "spurious 8259A interrupt: IRQ7" on the dhcpd server. The client then fails to get its IP setup.

The hardware seems ok as I can give the client a static address manually and everything works fine between it and the dhcpd machine.

Any thoughts?

you might have some hardware conflict with usb. if usb is compiled eth cards like to complain about irq resources problem

Ok, the machine has no usb controller - sorry if this is a stupid question, but how do I check for/remove usb support?

The 8259A is an Intel Programmable Interrupt Controler. I would think that your NIC is sharing an IRQ with another device, say your video card, sound card or something. Take a look at /proc/interrupts. -mk
