Re: irq nobody cared error

Hello,

I have a problem with irqs.

As soon our DVB card shares its IRQ with another device (in our case
it's eth2), dmesg says this :


Am not sure if this is relevant in any possible way. But once when I
plugged in a 3rd ethernet card, the Graphics card stopped working
immediatly - Monitor says "No Signal". (There is no loose contact
kinda mechanical stuff going on). So I am wondering if I faced a more
serious version of the problem that you are facing.

and the problem might in h/w only. I use an AMD 3000, with Gigabyte
MB, NVidia Nforce3 chipset. Do u happen to use a similar MB/chipset?
If so there might be some h/w issue.

We tried to change kernel versions, from 2.6.9 to 2.6.18, to change e100
drivers, but it won't fix the issue.

Does anyone have any idea or solutions? I used noirqdebug, irqpoll,
noacpi options already but in vain.

Can anyone guide me in the right direction please?

Thanks,

Dinesh
