Re: Error in rtw89 using Kernel 7.1.4

Ok, I'll try 6.6.9-arch1-1 for longer to see if I encounter the SER error.

I don't quite understand what you mean with:
> Therefore, if the infrequent SER doesn't bother your daily work, they suggest to just keep it as was.

Do you mean I should keep using the new kernels and ignore the error?
The disconnects aren't the end of the world, but they are annoying and
I was hoping I could help you improve the driver to fix the problem.
So I would like to continue, not just for myself, but to help improve
this for others too. I have an off the shelf prebuilt PC
(https://psref.lenovo.com/Detail/Legion/Lenovo_Legion_T5_26AMR5?M=90RC00UUGE),
I only added a second SSD, so I am sure I am not the only one with
this issue.

I have never built drivers before, and I don't have a lot of
experience with C, but I am a developer, so we can try that. I am
ready to try both options.

Something else I was wondering: In the error logs I see this message:
> firmware failed to ack for leaving ps mode

I am guessing ps mode is power saving mode, which is weird, because
the error happens during zoom calls and remote desktop sessions, which
use the connection constantly. So I would not expect the Wifi-Card to
go into power save mode here.
I read on https://wiki.archlinux.org/title/Network_configuration/Wireless
that in quite a few cases they suggest disabling power save.
I checked and power save seems to be enabled on my system:
$ iw dev wlan0 get power_save
Power save: on

Should I try to disable it? Would that give you any new information?

The arch wiki also contains a chapter specific to rtw89:
https://wiki.archlinux.org/title/Network_configuration/Wireless#RTW89
They suggest disabling ASPM-related features using the config below.
/etc/modprobe.d/70-rtw89.conf
  options rtw89_pci disable_aspm_l1=y disable_aspm_l1ss=y
  options rtw89_core disable_ps_mode=y

However this sounds like it affects notebooks, whereas I have a desktop PC.

Should I try this? Would that give you any new information?
