Oh yeah, it would be awesome to set such message...but I'm not sure how we can do it! If we know beforehand that the reserved memory amount won't work for your system, to show the message..why we don't just fix it?
The problem is that this is a policy, there is no technical mechanism (currently) that foresees that a quantity of RAM equals X is required for your system in order kdump to work. We have the heuristic (aka sets crashkernel to 192M), which is expected to work on the majority of machines. Hence, the recommendation for kdump users is to install the package and perform a dummy kdump, as you did! If it fails, go ahead and fine tune that. With the estimator I've pointed you in the last comment, things should improve, having a mechanism that will suggest a proper amount, pre-calculated on boot time. But until we get that merged, this situation is not ideal and will remain like this - I understand it's not the best, if you have a technical suggestion on how we could improve it, it's highly appreciated =) Cheers, Guilherme -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1931779 Title: kdump just hung out of the box To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/makedumpfile/+bug/1931779/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
