kernel panic at boot time

[baptx]

Since several weeks there is a kernel panic after the upgrade to linux-image 4.18.0-15-generic.
Do you have an idea why it happened and when it will be fixed?
Currently I have have to press several times the escape key when starting my laptop in order to select a working Linux kernel like 4.18.0-14-generic.

There is an error with the command:

bapt@dell:~$ apport-collect 1818392
dpkg-query: no packages found matching linux

But I guess the problem affects other people too and should be able to confirm.

[baptx (b4ptx)]

I cannot change the package name of this issue from linux to linux-image-4.18.0-15-generic.

[baptx (b4ptx)]

Can someone else reproduce the problem?

[baptx (b4ptx)]

A new kernel panic happened when upgrading to Ubuntu 19.04, any idea why? The workaround is to select an older Linux kernel version like 4.18.0-17-generic.

[baptx (b4ptx)]

I am using Dell XPS 13 Developer Edition, revision 2.

[baptx (b4ptx)]

A new kernel panic happened when upgrading to Ubuntu 19.10 and there is still no explanation on this bug report. I guess I will have to choose another Linux distribution if it continues.

[baptx (b4ptx)]

Always at boot time. I have to select the previous Linux kernel.

[Kai-Heng Feng (kaihengfeng)]

Please test 20.04 daily image.
If the issue persists, please attach log or screenshot here.

[baptx (b4ptx)]

I prefer to avoid installing daily images on my laptop since I use it for work. But anyway I noticed the problem is fixed after an update on Ubuntu 19.10. The problem has been fixed several times in the past and then after another update, it will come again. It would be nice to hear where the problem comes from and what has changed to fix the problem.

[baptx (b4ptx)]

The kernel panic happened again at boot time after upgrading to Ubuntu 20.04. Why is there no permanent fix?

[baptx (b4ptx)]

*happens again
