Yo, I just installed cockpit and I got a notification about failed to start service

Crash recovery kernel arming

. What should I do?
but

I’ve already tried editing sudo nano /etc/kdump.conf

and setting

crashkernel=128,

but I can’t find

KDUMP_COMMANDLINE_APPEND

. I also restarted kdump.service with

sudo systemctl restart kdump.service

, but it failed with the error message Job for kdump.service failed because the control process exited with error code. See

“systemctl status kdump.service” and “journalctl -xe” for details.

help figure out what’s wrong? What should I do?

add to the KDUMP_COMMANDLINE_APPEND line in /etc/sysconfig/kdump is what i think the docs suggest
currently mine is set to KDUMP_COMMANDLINE_APPEND=“irqpoll nr_cpus=1 reset_devices cgroup_disable=memory mce=off numa=off udev.children-max=2 panic=10 acpi_no_memhotplug transparent_hugepage=never nokas
lr hest_disable novmcoredd cma=0 hugetlb_cma=0”
