warning: file-aligned section .text extends beyond end of file

[David Henningsson]

When running a dist-upgrade, I received the following warning:

Setting up linux-signed-image-4.4.0-2-generic (4.4.0-2.16) ...
warning: file-aligned section .text extends beyond end of file
warning: checksum areas are greater than image size. Invalid section table?

Note: I've tried booting the kernel with dmesg enabled, it seems to boot just fine. See https://launchpadlibrarian.net/235948033/CurrentDmesg.txt for when I booted it.

Status changed to 'Confirmed' because the bug affects multiple users.

Problem still occurs, possibly. I got the same message this evening during an 'apt dist-upgrade' run:

Just got this for linux-signed-image-4.4.0-22-generic (4.4.0-22.40).

Just got this warning when installing linux-signed-image-3.13.0-101-generic (3.13.0-101.148) on Trusty.

[Jean-Pierre van Riel (jpvr)]

Same, here, this message makes me fear that my system won't be able to boot with the new kernel.

This seems related? https://bugs.launchpad.net/launchpad/+bug/1071562

This suggests it isn't as serious as it sounds? http://www.rodsbooks.com/efi-bootloaders/secureboot.html. However, no actual explanation.

Just got this warning when installing linux-signed-image-4.4.0-51.72-generic:

warning: file-aligned section .text extends beyond end of file
warning: checksum areas are greater than image size. Invalid section table?

And the new kernel won't boot.

The old one still works.

Got this message while update to linux-signed-generic:4.4.0.51.54. System boots and work correctly.

By the way, my motherboard does not support secure boot
