I know I'm mostly talking to myself...

... but taking down the one "bad" blade didn't stop it from rebooting. So dropped it to 7 blades, to see if it makes any difference. T-minus 30 minutes till next reboot, or maybe not.
Thinking I will try 5 next if 7 doesn't work... and frankly if 5 doesn't work, I'm going back to 10, rebooting or not, I'd still rather be mining with reboots than limping along.
