 I have removed the failing disk from the LaCie USB-casing, and have connected to 
 another USB device. Now the USB error has disappeared, but when I boot without 
 the disk and then attach it I still get this kernel trap and a rebooting system 
 when it automatically starts the ZFS pool after the missing disk is found:
 
 kernel trap 12 with interrupts disabled
 
 Fatal trap 12: page fault while in kernel mode
 cpuid = 0; apic id - 00
 fault virtual address  = 0x11

 Cannot dump. Device not defined or unavailable
 Automatic reboot in 15 seconds - press a key on the console to abort
 Rebooting...
 cpu_reset: Stopping other CPU's
 
 Would upgrading to another FreeBSD environment help?
 
 Best,
