Public bug reported: I have been running the rtw89-integrated driver for a few weeks now, since it has been available in impish-proposed, to no problem.
As mentionned on https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1954438 I did had to use suspend/resume and (immediately) after that I started to notice poor latency over my local network. It was a behavior I suffered from a while ago, without the use of suspend/resume, as mentionned on https://github.com/lwfinger/rtw89/issues/36#issuecomment-990913111 and that was avoided by setting rtw89core module's parameter disable_ps_mode=Y to disable low power mode. I have been able to run without that parameter fine for several weeks, the latency being correct, even when running on battery. After a suspend/resume (and the required unloading/reloading of modules for rtw89), I have been suffering from very poor latency, mostly on IPv6, either on battery or not: $ mtr --report -4 -n serveur.home Start: 2021-12-10T13:24:39+0100 HOST: portable-alex Loss% Snt Last Avg Best Wrst StDev 1.|-- 192.168.1.98 0.0% 10 5.5 3.7 1.1 5.5 2.0 $ mtr --report -6 -n serveur.home Start: 2021-12-10T13:24:58+0100 HOST: portable-alex Loss% Snt Last Avg Best Wrst StDev 1.|-- 2a01:xxxx:xxxx:xxxx:bdf9: 0.0% 10 4.8 82.4 4.8 253.4 81.5 This is 100% not related to my network or anything else. Rebooting the system makes it working well again, and issuing a suspend/resume cycle it comes back. It's likely to be an upstream issue, but I am wondering if some of the mode recent changes on v7 of the rtw89 driver might not help and fix that. ** Affects: linux (Ubuntu) Importance: Undecided Status: Incomplete -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1954439 Title: rtw89 shows bad latency afer a suspend/resume Status in linux package in Ubuntu: Incomplete Bug description: I have been running the rtw89-integrated driver for a few weeks now, since it has been available in impish-proposed, to no problem.
