On the disk is a bootable 9.0 FBSD. The disk was used as boot disk on a i386 atom system. Then using it on a amd64 system with zpool import -o altroot=/mnt -f zroot orked fine. After shutting down the system with shutdown -p now the disk can no more be used. Issuing zpool list or zpool import -o altroot=/mnt -f zroot on the amd64 system panics the kernel. Also attaching the device to the i386 system panics the atom system. The failed assertion is in the file ddt.c line 129. I have a picture of the panic. My assumption is, that there is a problem with deduplication (because on the disk is one dataset with switched on dedup). The data of the disk is no more accessible. >How-To-Repeat: Using this disk, plugging it to either the amd64 or the i386 system Issuing zpool list and the panic shows up If you have any patches to test I will do this. I will keep the disk in this state for some time. If I can help in any way, please ask me. >Fix: >Release-Note: >Audit-Trail: >Unformatted:
