I would like to add the following link:
https://gist.github.com/eliottness/ded6bce8163689dc426732d0670c7a28 which
contains more background and tests done.

There are several people hit by this issue, which was not a problem in older
kernels. Not sure when it was introduced, but my machine has run more than a
year stable, until an update caused it to take a newer kernel... since then I
have such a failure on average each 14 days.
