Hi,

I get a lovely panic everytime i try to import my pool.

panic: page fault
...
#5 ... calltrap
#6 ... zio_vdev_io_start
#7 ... zio_execute
#8 ... zio_ioctl
#9 ... zio_flush
#10 ... vdev_config_sync
#11 ... spa_sync
#12 ... txg_sync_thread
#13 ... fork_exit
#14 ... fork_trampoline

This is for a funky config in which one half of a zfs-mirror sits on a 
local gpt partition and the other half on a local file on a ufs volume 
(dont ask why).

The machine is running a 8.2-stable, compiled on 5th Sept 2011.

Maybe r226617 fixed this?
Any idea how to get it back alive?
