Description Martin Pitt 2021-03-02 06:56:06 UTC 
Description of problem: kdump is broken in Fedora 34. It works fine in 33 and RHEL 8.3/8.4.

This was spotted by cockpit's integration tests in https://github.com/cockpit-project/cockpit/pull/15350


Version-Release number of selected component (if applicable):

kexec-tools-2.0.21-5.fc34.x86_64
dracut-051-1.fc34.1.x86_64
kernel-core-5.11.1-300.fc34.x86_64


How reproducible: Always


Steps to Reproduce:
1. Enable crashkernel=: In /etc/default/grub, append crashkernel=256M to GRUB_CMDLINE_LINUX
2. grub2-mkconfig -o /boot/grub2/grub.cfg
3. mkdir /var/crash
4. reboot
5. systemctl start kdump

Actual results:

× kdump.service - Crash recovery kernel arming
     Loaded: loaded (/usr/lib/systemd/system/kdump.service; disabled; vendor preset: disabled)
     Active: failed (Result: exit-code) since Tue 2021-03-02 06:52:33 UTC; 2min 54s ago

Expected results: kdump.service starts

Possibly related to this SELinux violation?

Comment 2 Matej Marušák 2021-04-05 09:08:29 UTC 
When this issue was opened, `/sys/kernel/kexec_crash_size` would contain `256`. Right now it is `0` and still `systemctl start kdump` fails.
I am not sure if this is different issue or the same one hitting the system just slightly differently so I am just adding it here.

Here I provide difference in packages between the image on which this issue was originally reported and this new one:

Cockpit CI cannot reproduce this anymore, so seems fixed.
