not sure what/when is the last good kernel, but can defiantly
reset a few to find one, then do a bisect on this.
(keep in mind I'll be leaving for a few days, so might do this
until over the weekend or something).
maybe this is cable related i.g.
using a firewire cable from the apple
store($40big ones),on an imac gives this
message., but if I use the
cable from the firewire(slighty thicker), on
a macbook, I can do the above mount,cp,unmount
with the kernel, and hit nothing.(both xserver
and all its libs etc.. and the kernel both seem to
be pretty large to transfer).
