[Cristian Aravena Romero (caravena)]

Did this issue start happening after an update/upgrade? Was there a
prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v4.19 kernel[0].

If this bug is fixed in the mainline kernel, please add the following
tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag:
'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as
"Confirmed".

Thanks in advance.

Checking the logs, it appears that there are two video cards, but according to the backtrace there are problems with the video card 'Intel'.

Please reproduce the problem again, reboot and then immediately run:

  journalctl -b-1 > prev_boot.txt

and send us the file 'prev_boot.txt'.
