Uhm... Sorry for that, I seem to have triggered some keyboard shortcut.

Now... One more interesting observation. I tried to boot 4.18.0-14 without
splash screen. For this I edited the entry (using "e" in grub) to removed the
lines
load_video
gfxmode $linux_gfx_mode
and also the paramters "quiet" and "splash" from the kernel commandline. The
last line that was written to the screen was
[ 3.094622] fb: switching to inteldrmfb from EFI VGA
after that, the computer continued booting but the screen stayed blank.
The BUG entrie and call trace (etc.) appear a few lines after that in
the dmesg output.
Regards,
Jan

Title:
4.18.0-14 doesn't boot past grub
Status in linux package in Ubuntu:
Confirmed
Bug description:
4.18.0-14 doesn't boot past grub for me in thinkpad t510i. 4.18.0-13
worked fine. I had to revert back to 4.15 kernel. I'm using a distro
that is based off of Ubuntu 18.04.
System info:
CPU: Intel(R) Core(TM) i5 CPU M 520 @ 2.40GHz
4 cores/threads
2400.00 MHz
RAM: 7.59 GiB
I'm not sure how to provide crash info, as the kernel doesn't boot.
