Description jp-dev 2022-06-22 17:12:43 UTC
Created attachment 1891959 [details]
kernel logs from journalctl, all three cases

1. Please describe the problem:

After an update of kernel, the wi-fi device fails to initialize, Network Manager does not see the device.
The green led would usually light up, but it doesn't.

This USB device is described as:
Bus 004 Device 003: ID 2357:010c TP-Link TL-WN722N v2/v3 [Realtek RTL8188EUS]


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

5.18.5-200


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 :

The problem first appeared with kernel 5.18.5-200.fc36.x86_64.
The kernels which worked are 5.17.14-300.fc36.x86_64 and previous ones.


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

On reboot, this consistently fails on the kernel 5.18.5, and succeeds on the kernel 5.17.4.

This log entry is seen: `r8188eu 4-3:1.0: _rtw_init_xmit_priv failed`
The OK boot does not have such a log entry.


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``:

This problem does not occur in Rawhide, and the network is fine.
*However* the boot log shows a kernel warning with `r8188eu` in the backtrace.
I am attaching that log also.


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

Yes, the module `vhba` from the official repository.

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 attachment.
