That's actually a squash of a recent patch. See
<https://chromium-review.googlesource.com/189239>. I've specifically
seen at least one case on my device where it needed 888 retries at
bootup!

...on my really old Chromebook, it seems to get into a bad state if it
sits on my desk for a long time. After I use it a bit it rarely needs
more than 10 retries.
