Since Ubuntu 19.04 / Disco reached it's end-of-life on January the 23rd:
https://lists.ubuntu.com/archives/ubuntu-announce/2020-January/000253.html
the entry that marks this ticket as affecting 'Disco' is changed to 'Won't Fix'
and with that the overall status adjusted, too.
(Notice that this did not happen with Eoan and kernel 5.3.)

Title:
Extreme Delayed Reboot with Disco on Ubuntu LPAR s390x (5.0.0-38)
Status in Ubuntu on IBM z Systems:
Won't Fix
Status in linux package in Ubuntu:
Won't Fix
Bug description:
With the proposed Disco kernel (5.0.0-38)
I can't reboot the s390x LPAR node s2lp4
When I tried to reboot the system it will render the system into a
"Not operating" status.
I tried to watch the output from the Integrated ASCII console and the
Operating system messages from IBM Hardware Management Console. But
there is nothing interesting there
From Operating System Messages, it ends at:
[ OK ] Reached target Final Step.
[ OK ] Started Reboot.
[ OK ] Reached target Reboot.
And never proceed from this point. And HMC shows "Not operating"
From Integrated ASCII console it just shows the login prompt, never
prints any other message.
Reboot works fine with older kernel (5.0.0-37)
