I believe the bisect is done:
Building this commit causes the ethernet to work after reboots. (a PHY
problem seems to make sense as there's no link lights).

I've found that on stock focal the ethernet device on my ASUS ROG Strix

Few final comments on the work I did to narrow this:
* Issue is present in ubuntu but not in mainline (4.15.17 I think is closest? I
have tried a bunch though 4.15.0, 4.15.18, 4.15.16...)
* I compiled mainline kernel 4.15.17 from linux-stable with ubuntu config from

Christopher Penalver:
I figured out the modules thing. It seems older kernels don't have
separate debs for the modules. I needed the extra package regardless (if
both linux-modules-extra and linux-image-extra were missing I don't
think the test is right).
I went back further:
4.14.0-16-generic_4.
Small update. I've gone back to try and see what I can learn from
installing pre-built kernels:
1) for some reason when I reboot sometimes I see the grub screen in
mirror mode and sometimes one monitor is blank. This issue happens
whenever grub is mirrored between both monitors. It is always mirro
re building. I think i've gotten it building. "time fakeroot
debian/rules binary" takes a long time, but seems to be working
re your questions:
1) it's consistent. only when booting right after grub I get a kernel crash.
Every time when my monitor is connected via the HDMI connector on my laptop.
I also found the mapping between ubuntu versions and mainline versions
and so tried mainline linux-image-4.15.17-041517-generic which also did
not exhibit the issue.
