hello
To push zfs, I launch 2 scrub at the same time, after ~20 seconds the
system freeze:

I found a deadlock too. If it's reproducable for you, can you try this
patch:
I reproduce it after 30 minutes, si I try you patch.
http://people.freebsd.org/~pjd/patches/zgd_done.patch
when I try to load zfs.ko I get:
# kldload zfs
link_elf: symbol kproc_create undefined
kldload: can't load zfs: No such file or directory
What must I add to my config to resolve this symbol / problem
Ouch, you don't use HEAD. Try changing kproc_*() to kthread_*().
It load correctly now...
Moreover, no deadlock after multiple scrub in // and some buildworld to
make sure...
look fine for my config :-)
Just to give credit to zfs, scrub encounter 2 IO errors without impact
on my data :)
