Sill having this issue. Sorry, which version of gcc may fix it? Here my

Also tested the vanilla 4.15-9 : no trouble here too
Then reloaded the ubuntu 4.15.0.12 : again no more issue. Looks like the
new gcc upgrade has resolved some problem.

Booting with 4.16-rc5, that error is not seen with that vanilla kernel
oem@ubuntu:~$ journalctl -b | grep intel

As said on top of that report, that error is seen for the first time using the
latest supported kernel. This same kernel (4.15-7) was not exposing that error
until yesterday (check journalctl daily), so might have some relationship with
gcc recent changes.
Will install vanilla 4.16-rc5 and
Did this issue start happening after an update/upgrade? Was there a
prior kernel version where you were not having this particular problem?
Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v4.16
