Bug#311357: via-rhine still not working...

Hi

I tried your latest patched 2.6.8 and 2.6.11 kernels on my home firewall.

(The home firewall was working fine with a 2.4 kernel last week, and
had been for many months. The hard disk failed, so I thought I would
test the new distribution and 2.6 kernel with the new disk.  Apart from
a replacement hda, the hardware is exactly the same. I am now *using*
raid !)

The via rhine driver in the new kernel is much better in that it actually
appears as an eth* device, and it works by itself.  As previously
reported, this was not the case with the 2.6 kernel in the 3.1r0
distribution.

BUT

When you have the via-rhine sharing an interrupt with another netcard
as I have, it dies horribly.  The via-rhine is my private network,
and the dec tulip the internet.

Both kernels fail, here I am running your 2.6.11

==========================

Here is a log for a controlled experiment: unload (with modprobe -r)
the via-rhine, unload the de2104x, load (with modprobe) the via-rhine,
load the de2104x, up eth0, (you can now do stuff on the private network),
up eth1, bang missing interrupt handler.

==========================

With the interrupt disabled, neither card works, despite being 'UP'.
This is repeatable, and the same happens at boot time.
Look forward to your comments.

Thanks
