Various 2.6.... CentOS (RHis the lowest but RH puts in lots of
patches, so it's impossible to compare, Debian Etch has 2.6.15+ and
Ubuntu has 2.6.15+)

Occasionally but not repeatably the followin messages after 'ifconfig
eth0 down/up'

...eth0: no link during initialization
...eth0: link is not ready
...eth0: ADDRCONF (NETDEV_CHANGE link becomes ready)

Excellent wag, but what to do if this is the case? The bios has been
flagged to turn off the internal sound card, but no other changes.

Windows appears to be immune to the changes, ie dhcp able to get an
address - 192.168.0.2 with gateway 192.168.0.1 which is the expected
assignment by the router for this particular cable.

My next experiment will be to rip out the soundcard again and return
to the status quo ante.
