[systemd-devel] kexec -p option does not cause a reboot on panic

[Dey, Megha]

Hi,

I was testing kexec on systemd (Ubuntu 16.04). Here are the steps I follow:


1.       Install a kexec aware kernel (all the configs needed for kexec are enabled)

2.       Give the following command after making sure we have set up crash memory: kexec -p --initrd=<initrd> --reuse-cmdline <vmlinuz>

3.       Check /sys/kernel/kexec_crash_loaded(it is 1)

4.       Generate a panic: echo c >/proc/sysrq-trigger

Even after waiting for a while, I see that no reboot is  happening. However, the kexec -e option works just fine.

Kexec -p works as expected on Ubuntu 14.04(which uses systemv)

Has anyone seen this issue before? Is there any additional step required that I may have missed? It would be great if I could get some pointers.

Thanks,
Megha
