kernel panic after upgrading from 19.04 to 19.10

[Jonathan Kamens]

I have Package: linux-image-5.3.0-10-generic, Version: 5.3.0-10.11 after upgrading from 19.04 to 19.10 today.

I get a kernel panic on boot, before I'm asked to enter the passphrase for my hard drive.

I obviously can't cut-and-paste the kernel panic text, but I took a photo, attached.

+1, same issue here after upgrading from 19.04 to 19.10 (development).

This is the same spec machine that is listed above: Thinkpad X1 Carbon 7 gen.

note: Kernel panic is before the system asks for SSD password.

See LP: #1844784

[Eduardo Silva (edsiper)]

thanks for the hints.

I tried the workaround of disabling secure boot and it did not panic and the system started.

But I would like to keep secure boot enabled, note that booting 19.10 with the Kernel linux-image-5.0.0-29-generic from 19.04 works properly.

I am no longer seeing this kernel panic on boot, even with the same kernel package that was panicking before. Can't explain what changed. *shrug*

Thanks for the bug report. The attached screenshots show this is the same issue as we're tracking in bug 1845454 now.
