Kernel crash when booting laptop with hdmi monitor connected
To manage notifications about this bug go to:
Tried following kernel versions with system upgraded w/ or w/o nvidia-
driver-390 (version 390.116-0ubuntu0.18.04.1) installed. Booting with
HDMI cable connected doesn't have any problem for X, and I got dual
screen working as expected.

Kai-Heng Feng: I did some more testing and I don't see the problem in the
cosmic proposed kernel 4.18.0-9.10.

procedure.

screws with the startup timing. Do you know of a way to change the grub

I'll work on this when I find some time.
In the meantime, can you try Cosmic live USB/CD? It uses 4.18 kernel.

Yes it does. I just confirmed the issue is still present in
4.15.0-34-generic. I also upgraded my bios to the latest 1.2.8. See
attached syslog which contains backtrace. I don't notice any difference.
I was also able to find another workaround by removing "splash" from the

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

Sandy Patterson, the next step is to fully reverse commit bisect from
