I can confirm now, the problem is definitely related to the -p8 update.
I rolled back now to -p7 using `freebsd-update rollback`.

I removed complete ccache in `/var/cache/ccache`
I removed all build poudriere packages and rebuild all packages

System is now up and running again.

This all works even if poudriere jail is using -p8. No need to downgrade 
the jail/base version poudriere is using.
It is caused by the kernel so the ZFS patch seems to be broken and -p8 
should maybe not rolled out to not break more systems of users.

My gut feeling is on the last one, but I haven't tried analyzing that
yet (and I've never worked with that code before, so I'm not sure if
I would spot the problem if I did).

Also, I've to pour one for git: just creating a local branch and revert
and poke around in there is so much easier than it ever was with svn.

example for those who still want to go back).</pre>
