I didn't assume "ignore", just wondered if messages got through. Thank
you for explaining; I will be more patient. :-)

> 4.14 stable (that's before the big overhaul of the vector/msi code)

Haven't been able to boot 4.14 yet (as I already have a newer GCC).
Still trying to properly compile.

Meanwhile, here it is for 4.9, which is the latest Debian-provided
kernel and worked:

I will keep trying 4.14, unless you say otherwise.

I tried diffing -u but I could not interpret the result.

Thank you for your help,
Octavio.
