2. What is the Version-Release number of the kernel:
kernel-5.2.0-0.rc2.git1.2.fc31.s390x


3. Did it work previously in Fedora? If so, what kernel version did the issue
   *first* appear?  Old kernels are available for download at
   https://koji.fedoraproject.org/koji/packageinfo?packageID=8 :

was also present in 5.1.0-0.rc3.git1.1.fc31.s390x


4. Can you reproduce this issue? If so, please provide the steps to reproduce
   the issue below:

yes, just boot


5. Does this problem occur with the latest Rawhide kernel? To install the
   Rawhide kernel, run ``sudo dnf install fedora-repos-rawhide`` followed by
   ``sudo dnf update --enablerepo=rawhide kernel``:

yes

6. Are you running any modules that not shipped with directly Fedora's kernel?:

no


7. Please attach the kernel logs. You can get the complete kernel log
   for a boot with ``journalctl --no-hostname -k > dmesg.txt``. If the
   issue occurred on a previous boot, use the journalctl ``-b`` flag.

Comment 2 Dan Horák 2019-07-03 13:00:32 UTC
Rechecked with kernel-5.2.0-0.rc6.git2.1.fc31.s390x and looks like it got fixed in between.
