I'll see about doing that tonight, it did show up as eth1 in ifconfig
though.  It's a wireless card though, I don't know if that has some
impact on this.

It's really annoying. :)  I'm working around it though.  It's still be
nice if there was a way to kill/restart the shell on that console
somehow though, or start up another shell on another console.

Right, do it once and cache the info, don't redo it every time, that's
silly.

I tend to agree, but I have no idea which module it was trying to load..
Does it log which module it's trying to load something?  It really
should, if it doesn't...  Then you could just flip to con-3 or whatever
one is the tail -f and see.

Yeah, I did find out though that I can ctrl-c and it dropped through and
I finished the install and the system appears to be operational, though
I can't seem to find drivers for the installed kernel for my wireless
card (even though I know it showed up as eth1 in the boot system, and I
think I recognized the module in the install, I'll have to check that
again).

Thanks,
