[Voyage-linux] Most stable Voyage kernel for USB?

[Punky Tse]

Robert,

I searched the archive about your post, I found that you are able to run 
ubuntu in Mini-ITX hareware, so can you install the kernel package used 
by ubuntu to voyage from the following URL:

http://debian.cn99.com/ubuntu/pool/universe/k/kernel-image-2.6.7-i386/kernel-image-2.6.7-1-k7_2.6.7-1ubuntu2_i386.deb
  or
http://debian.cn99.com/ubuntu/pool/universe/l/linux-source-2.6.11/linux-image-2.6.11-1-386_2.6.11-0.2_i386.deb

wget it and do a dpk -i.  I don't know which kernel used by ubuntu so 
please find the one match.  If you don't see problem about USB when 
using ubuntu kernel in voyage, it should probably be kernel patch 
problem or related to kernel config.  If so, please send me the kernel 
config which should be found in /boot.
