Hi,
I am using FreeBSD 10-CURRENT of 15 september on a SHEEVAPLUG ARMv5
machine.
I did these steps:
newfs_nandfs /dev/gnand0s.root
mount -t nandfs /dev/gnand0s.root /mnt
cd /; tar cf - / | tar -C /mnt -x -f -
I did ctrl-c because I found it was tar-ing /mnt into /mnt/mnt.
rm -r /mnt/mnt/*
tar --one-file-system -c -f - / | tar -C /mnt -x -f -
That gave the panic below. What information can I provide to solve this?
Ronald.
