Hi Linus,

Sorry for the inconvenience, indeed, the regression has been fixed.
Woohoo.. And more than fixed, it looks like. Not that I looked at
historical data, I'm not sure how much this number normally
fluctuates. I'm assuming the stddev is just a per-boot "do it a few
times" rather than any long-term thing?


Hi Linus,

Yes, the stddev is not very precise, we usually boot more than three times to
get the value.
