Steven,

This will need someone with better hardware skills than I have. I can't
offer a solution. But can you please send me your entire dmesg output
anyhow? I only want to see the dmesg stuff if it is simple and easy for
you to do that. I don't mean to cause you hours of manual typing -- if
that is the case, don't bother sending it to me. It's too much work.

In my mind, plugging in a usb flash drive is pretty simple. You write
the dmesg output to a text file and put the text file on the flash
drive. Then walk it to an internet enabled machine and email it to me.

dmesg > dmesg.txt 

Also I'd like to see your ifconfig output which has to be done as root:

ifconfig > ifconfig.txt


Thanks

Bob Cochran
