Title:
rtw89 shows bad latency afer a suspend/resume
Status in linux package in Ubuntu:
Confirmed
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.
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

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.
