2. What is the Version-Release number of the kernel:
Linux localhost 5.1.1-300.fc30.x86_64 #1 SMP Sat May 11 17:15:05 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux


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 :


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


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``:


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


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.
