freebsd-xfce:
I have a computer with Intel DQ67SW motherboard, Intel Core i7-2600S
CPU, 8 GB RAM, 16 GB SSD.
I installed:
FreeBSD-11.0-RELEASE-i386-memstick.img
I selected MBR partitioning and encrypted ZFS on root during installation.

If I use 'dd' to take an image of the system drive (using Debian 7 on a
Pentium D 945 computer):

When I boot the cloned drive in the same computer, Xfce applications
refuse to start. For example, selecting Application Menu -> Terminal
Emulator issues a pop-up:
Failed to execute default Terminal Emulator.
Input/output error.
Switching to the console (Ctrl+Alt+F1), I see the following error messages:
vm_fault: pager read error: pid 1023 (python2.7)
vm_fault: pager read error: pid 1040 (xfce4-terminal)
What is the problem?
How do I fix it?
TIA,
David
