Sure, I will turn it off and report back.

This all started with similar lockups even without the SMART monitor, and I
used the monitor as a reference because it would reliably lock up one of the
channels right away.

I have at least one other thing to try that used to trigger bad things -
creating a geom_stripe array. However, since it really messed my system up
last time I tried it I'll wait until right after a full backup to run the
test.

Thank you for your efforts Søren!
