The Launchpad site having difficulties, I don't know if the email bridge will be
sufficient to reach you.

The kernel team has asked to see if you could test the kernel in the following PPA :

  ppa:canonical-kernel-team/unstable

The kernel version is 4.8.0-17.19 and it is the kernel which may potentially
make it to the image. So if you can verify if the crc32c issue is present or not
on the ppc64el, this would be very helpful.

Kind regards,

...Louis
