Hi (Please excuse my bad english),
I think is there a bug on my linux box : I hope you can say me that it is really a bug, or if i have to consider myself as bug :)
If i boot my system/kernel with usb devices plugged, eth0 is detected but unusable. I unplug the usb devices, kernel boot, and eth0 is usable. The bug is reproducible as much as necessary.
More informations : (if you need more informations, ask, i will reply)
When i say that eth0 is unusable, i can see there no dhcp request can make a success.
I've seen the bug with : linux-2.6.24-gentoo-r8 linux-2.6.25-gentoo-r5
I can test with a vanilla kernel (without the gentoo patches) but i "think" is there no link with the gentoo patches. (Ask if necessary)
