I suppose I should have made it clear that just changing the amount of memory reserved was not sufficient.
Perhaps it would be useful to print a message saying "hey, I know we set something by default, but we don't expect that to actually work, so you should probably test and adjust it"? Because it sounds like it's not expected to work out of the box, and configuring it to "on, but doesn't actually work or warn you" when you install the package seems worse than not configuring it, similar to how I wouldn't expect installing ccache to result in it sticking itself in my PATH, reporting "ccache enabled and working" when asked, but then defaulting to a max cache size of 4 kilobytes. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to makedumpfile in Ubuntu. https://bugs.launchpad.net/bugs/1931779 Title: kdump just hung out of the box Status in makedumpfile package in Ubuntu: Fix Released Bug description: I tried installing kdump-tools (1.6.7-1ubuntu2.2) on my up to date 20.04 system, installed specifically to try reproducing a bug. But when I tried, after kdump-config status reported "ready to dump" on reboot, echo 'c' | sudo tee /proc/sysrq-trigger, it printed the panic to console and then just hung forever. After some blind guessing and twiddling both variables, I found that crashkernel=512M-:256M works on this particular setup.
