oops in kernel log

1. Please describe the problem:

5.1.7 has 1+ oops/day which result in stuck processes and terminal sessions, requiring a reboot.

2. What is the Version-Release number of the kernel:

5.1.7-200.fc29

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 :

Didn't seem to have this under 5.1.6-200.fc29 and earlier kernels

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

No specific steps to reproduce, just happens after a while under normal use.  I'm attaching trace.

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``:

"Error: Unknown repo: 'rawhide'" - is this feasible under F29?

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.
