[Daniel Mehrmann (daniel-mehrmann)]

Kernel module crash after dist-upgrade from 18.04 to 18.10. This happens after every boot. I rebuild dkms modules twice. Everything else runs smoothly :-)

[Ubuntu Kernel Bot (ubuntu-kernel-bot)]

This bug is missing log files that will aid in diagnosing the problem. While running an Ubuntu kernel (not a mainline or third-party kernel) please enter the following command in a terminal window:

apport-collect 1802050

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

[Tamer Hassan (tamer.hassan)]

redhat fixed it https://bugzilla.redhat.com/show_bug.cgi?id=1570493
debian followed also with the same patch https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=901919

still affects me:

kubuntu 18.10
linux-image-4.18.0-13-generic = 4.18.0-13.14
nvidia-driver-390 = 390.87-0ubuntu1

[Ilya Brik (ibrik)]

Still reproducible on 4.18.0-15-generic

Also, worth to note, I had similar crashes before upgrading to nVidia, by using Nouveau driver. See: https://bugs.freedesktop.org/show_bug.cgi?id=100567
