Description K. Anderson 2021-08-09 21:56:57 UTC 
1. Please describe the problem:
Performing a large amount of network i/o causes the Intel driver to reset due to a firmware error. After that performance drops to around 500Kb/s till I disable networking and reenable it.


2. What is the Version-Release number of the kernel:
5.13.7-200.fc34.x86_64


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 :
Unknown but I had similar issues with an Intel AX201 on Fedora 33


4. Can you reproduce this issue? If so, please provide the steps to reproduce
   the issue below:
Performing large network transfers seems to trigger the problem more often but I have not found a way to reliably trigger it outside of that.


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 1 K. Anderson 2021-10-22 22:32:24 UTC 
I can reliably reproduce this by running iperf and I can consistently get a firmware reset in around 5 minutes even with the latest Fedora kernel
Comment 2 Adam Miller 2021-11-22 14:17:22 UTC 
I'm experiencing this issue on the latest Fedora 35 kernel.

Comment 6 K. Anderson 2022-01-04 01:36:36 UTC 
Hi Christian,

Since you are using a different adapter and firmware version it might be best to open a separate bug report as I am not sure it is the same issue.

- Kevin
Comment 7 Christian Kujau 2022-01-04 14:41:21 UTC 
Sorry about that, I just noticed I reported the same for AC 8265 in bug 2024670. Again, sorry for the noise.
Comment 8 Ben Cotton 2022-05-12 15:51:09 UTC 
This message is a reminder that Fedora Linux 34 is nearing its end of life.
Fedora will stop maintaining and issuing updates for Fedora Linux 34 on 2022-06-07.
It is Fedora's policy to close all bug reports from releases that are no longer
maintained. At that time this bug will be closed as EOL if it remains open with a
'version' of '34'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, change the 'version' 
to a later Fedora Linux version.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora Linux 34 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora Linux, you are encouraged to change the 'version' to a later version
prior to this bug being closed.
Comment 9 Ben Cotton 2022-06-07 22:43:53 UTC 
Fedora Linux 34 entered end-of-life (EOL) status on 2022-06-07.

Fedora Linux 34 is no longer maintained, which means that it
will not receive any further security or bug fix updates. As a result we
are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release.

Thank you for reporting this bug and we are sorry it could not be fixed.
