dmesg for an affected boot 5.10
I saw some iwl firmware updates go by, so I decided to give new (non-rawhide) kernels another try. Still having the problem. So I'm downgrading to 5.8 again. 5.10.14-200.fc33.x86_64 #1 SMP Sun Feb 7 19:59:31 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux I tried 5.10.16-200.fc33. Similar problem. It lasted somewhat longer, that could be chance, but eventually I could get no bytes through in a timely manner. 5.8.15-301.fc33.x86_64 never has a problem, I've been using it continuously except for my occasional few hours (tops) testing a new kernel. Still using 5.8 for weeks at a time where it acts normally. Saw a new kernel and IWL firmware update, and tried them out, 5.11.7-200.fc33. In a few minutes, wifi was unusable, a similar symptom as before. Tried out the newish 5.11.14-200.fc33. After a few minutes, same thing. Still no problems with 5.8.15-301.fc33 running for extended periods. Upgraded to Fedora 34, 5.11.17-300.fc34 carries the same defect. Still using 5.8.15-301.fc33. Tried out 5.11.19-300.fc34. Still a problem, though it took a few minutes to appear (this has happened on previous kernels, too). 5.8.15-301.fc33.x86_64 is still stable with wifi. I have noted in Fedora 34 that un-sleeping the laptop is no longer reliable, with either 5.8 or 5.11. Reproduced on 5.12.8-300.fc34 Reproduced on 5.12.12-300.fc34 I just spent a week on a different wifi network and I cannot reproduce this against a Linksys Velop mesh system (Wifi 6 5ghz) but I can against my usual Orbi mesh (also Wifi 6 5ghz). Reproduced on 5.15.18-200.fc35. I'm still using 5.8.15-301.fc33.x86_64 to make this laptop usable. 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 It is Fedora's policy to close all bug reports from releases that are no longer maintained.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. This resolved to me. Perhaps a new kernel caused it, but I think much more likely is a relatively large set of firmware updates sent by Dell. |
