Any chance = you could experimentally try that with this test? You won't get as many = I/O abort errors (since we don't print those), and we have a few more = workarounds for the reset path (though honestly, it's still kinda = stinky). >=20 > HEAD or RELENG_12, too? >=20 > HEAD is preferred, but any recent snapshot will do. I could not reproduce the problem for a couple of hours with an otherwise identical system but only 4 of these Intel drives. Now the same test system with 6 drives just as our FreeNAS boxes - instantly reproducible. I=E2=80=99ll upgrade to HEAD and see if that changes anything.
