Comment # 2 on bug 1167575 from Jiri Slaby

> Is this reproducible on your side ?

I don't know how -- it happened on midnight, so maybe some cron/timer... But it
happens irregularly (twice) as you could see.

So, how can I try to reproduce?

BTW, the first crash happened during update, but I have no crash file from
that:

qemu-ksm postuninstall does:
/usr/bin/systemctl daemon-reload
and then
/usr/bin/systemctl try-restart ksm.service
