out of curiosity, is this a root pool?
A second system of mine with a mirrored root pool (and an additional
large multi-raidz pool) shows the same symptoms on the mirrored root

once is accident. twice is coincidence. three times is enemy

I'll file a bug as soon as I can (I'm travelling at the moment with
spotty connectivity), citing my and your reports.
