It is for some environments, but that is something you would need to test locally yourself as I'm sure there are environments that 5.x is not ready to handle yet. It would be good to know if 5.x has the same problems with the network interfaces though, and a quick boot off of a CD can probably help determine that. > On Fri, 2005-01-14 at 14:30 -0500, John Baldwin wrote: > > On Friday 14 January 2005 02:02 pm, Ross Kramer wrote: > > > On Fri, 2005-01-14 at 13:11 -0500, John Baldwin wrote: > > > > On Friday 14 January 2005 12:57 pm, Ross Kramer wrote: > > > > Try adding 'device uhci' and 'device usb' to your kernel so that the > > > > USB controller (which shares the same IRQ) will probe.
