1. Please describe the problem:

On a particular (public Cafe) WiFi network, I observe my ath10k_pci device to crash. It claims to recover, but afterwards the network is unusable until restart or module unload/reload.

On a subjective level, the likelihood decreases with better reception.

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

5.1.18-300.fc30.x86_64

(But also happened with earlier versions)

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 :

No, I don't remember this working before. At least not in the 5.x timeframe.


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

Place laptop in a location with poor WiFi reception and wait. Happens every couple of hours.

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``:

Not tested.

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.

See above. I can provide more logs if required.
