eth1: too many iterations (6) in nv_nic_irq

[john]

Thanks Jim et al.

I saw that bug report when I was googling around. It seems to fit my
situation pretty closely, AMD processors, 64 bits, lots of traffic on
the LTSP facing interface, NVIDIA controller on the onboard NIC. It
looks like this problem is mended in the alpha2 kernel for Hardy Heron
but that "Hardly Helps"  :->  since I am afraid to move away from
Edubuntu 7.04 and the" linux-image-server" kernel (which I installed
to support <4G memory).

 Right now I am running   2.6.20-16-server. How do I go about
reporting to the maintainer of _that_ kernel? Or do I just need to
file a general bug report somewhere? I've never done that before so
I'd appreciate any advice you could give me.

Thanks again for the response.

John
