I am getting far enough into my system build that I don't want to go
back to square one everytime I mess up. So I decided I SHOULD be able
to clone my boot drive with:
sudo dd if=/dev/sdb of=/dev/sdc bs=4096 conv=notrunc,noerror; sync
And I did check that my working card is in sdb and the target is sdc.
Note that the target drive has been used for prior testing.
But this cloned card fails to boot, so there is something wrong with the
above command. Here is the end of what I am seeing on the console in
the boot:

============================================
I see these stack messages regularly even when things are working.
I hope someone can help me with the cloning, as it will really simplify
my testing.
thanks
