[Kernel-packages] [Bug 1743529] Re: Merge kexec-tools 2.0.16-1 from Debian: System hung with Kernel panic -not syncing: Out of memory message when crash is triggered.
kdump package is crap, because it is using a different image (initrd) than update-initramfs creates, so /boot/initrd.img-* != /var/lib/kdump/initrd.img-* . Yes, they may have the same name, but not the same content. What a hugh bullshit! So no wonder, why one has to waste several hours to find out, why /etc/systemd/network/* get not honored.

This bug was fixed in the package kexec-tools - 1:2.0.16-1ubuntu1 --- kexec-tools (1:2.0.16-1ubuntu1) bionic; urgency=low * Merge from Debian unstable. Remaining changes: - Default to not kexecing a kernel on boot in the automatically generated conffile - Don't call db_stop from the postinst. - Adjust INITCONFFILE to vmlinux if used - Add maintainer script helper to handle removal of conffile /etc/default/grub.d/kexec-tools.cfg has been removed. Handle it properly - Add Breaks: statement toward kdump-tools Starting with kdump-tools 1:1.5.9-6, this package takes over the addition of crashkernel= parameter which has been removed from kexec-tools. Make sure that it is upgraded accordingly. * New upstream release (LP: #1743529) kexec-tools (1:2.0.16-1) unstable; urgency=medium * New upstream release (Closes: #890818) * Updated pointer to kexec-tools home page (Closes: #888565) * Updtaed russian translation (Thanks, Lev) (Closes: #883918) * Remove obsolete configuration file (Closes: #868100) kexec-tools (1:2.0.15-1) unstable; urgency=medium * New upstream release (Closes: #876318, Closes: #854826) * Enable compressed kernel support for ARM64 - Manoj Iyer (Closes: #854093) * Updated Portuguese translation (Closes: #857728) * Updated German translation (Closes: #857737) -- Thadeu Lima de Souza Cascardo Fri, 23 Feb 2018 12:11:36 -0300 ** Changed in: kexec-tools (Ubuntu Bionic) Status: Confirmed => Fix Released -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to kexec-tools in Ubuntu. https://bugs.launchpad.net/bugs/1743529 Title: Merge kexec-tools 2.0.16-1 from Debian: System hung with Kernel panic -not syncing: Out of memory message when crash is triggered.
