Re: 2.6.7-rc1 breaks forcedeth

[Luis Miguel García Mancebo]

Hi:

(sorry with my poor english)

I have not been able to make my ethernet card to work in post-2.6.6 kernels. 
This is a nforce2 motherboard, and as Jeff pointed, nothing has changed in 
the driver (forcedeth), and the problem could be acpi or routing in the 
kernel. In fact, I have a "Disabling IRQ #11" message. Here is the dmesg:

P.S.: I have tested noapic, acpi=off, pci=noapic. But this doesn't fix 
nothing.
