Forgot to get the dmesg even though I did look at the dmesg output
(*facepalm*). There are no messages related to this in dmesg when this
occurs. But next time it happens, I'll get this to you to be thorough
and Just In Case.
i2cdetect -r 2
# When it's working:
i2cdetect -y -r 2

I tried on i2cbus 0 and 1, no changes there either.
This time I finally remembered to try hibernating (suspend to disk).
Resuming didn't fix the issue.
