[51]wb1# uname -rmp
12.0-RELEASE arm armv7
It is a wandboard qaud with iMX6 and 2G RAM.
I'm using two uSD cards with zroot.
I'm also using the same setup on a raspberry Pi1:
[13]time1# uname -rmp
12.0-RELEASE arm armv6
But 512MB RAM are to low for zroot.
It technically does work, but hoks up the CPU in arc_reclaim_thread when
a scrub runs and since it takes forever it always runs.
