However this is no longer true, and those params are no longer applied to the system's kernel param settings. [test case] install linux-crashdump (and kdump-tools). Edit the /etc/default/kdump-tools file to set the KDUMP_SYSCTL param to something other than default, e.g.: KDUMP_SYSCTL="kernel.panic_on_oops=1 kernel.panic_on_warn=1" reboot, or unload/reload kdump, to pick up the changes to the file. Check if the panic_on_warn param is set: $ cat /proc/sys/kernel/panic_on_warn 0 the problem does not seem to be with sysctl, as manually calling it does work: $ KDUMP_SYSCTL="kernel.panic_on_oops=1 kernel.panic_on_warn=1" $ cat /proc/sys/kernel/panic_on_warn 0 $ sudo sysctl -w $KDUMP_SYSCTL kernel.panic_on_oops = 1 kernel.panic_on_warn = 1 $ cat /proc/sys/kernel/panic_on_warn 1 [regression potential] TBD To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/makedumpfile/+bug/1845048/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
