it happened with the 4.18.* kernel as well. The machine came with Ubuntu
and 4.13 preinstalled, but I wiped it as soon as I could and installed
Debian. So I don't know if it would have worked with Ubuntu - the entire
setup was not suitable for my purposes, but I thought that 4.9 might be
too old for this hardware.
However, the machine came with a 1.3 BIOS, which I updated to 1.6 and
then to 1.7. I think, I had 4.18 together with 1.6 running, but closed
the corresponding bug report when I noticed that both a newer kernel and
a newer BIOS were available. Well, the situation compared has improved a
little, compared to that, but it is still very bad.

I mean, files on disk were destroyed. I noticed some because I use
etckeeper with git, and suddenly, I could no longer see my update
history because files in /etc/.git were corrupt to the point that no
"git fsck" or "git gc" could resurrect the tree.

Ok... In the BIOS, I set the corresponding parameter from "performance"
to "normal", which I hoped would be a more conservative setting, to
prevent exactly this problem.
