rtw_8821ce 0000:01:00.0: failed to send h2c command

[vturekhanov]

Describe the issue you are experiencing

I installed HAOS 14.1 to the new mini PC (fresh install from the scratch). It seems like everything works good but huge numbers of following host log lines while WiFi network is active (more than one line per second).

Switching to the wired network dramatically decrease number of that log lines: one line per couple of minutes.

What operating system image do you use?

generic-x86-64 (Generic UEFI capable x86-64 systems)

What version of Home Assistant Operating System is installed?

14.1

Did the problem occur after upgrading the Operating System?

No

Hardware details

G3 Mini PC Alder Lake N100 Intel 12th DDR4 8GB RAM 256GB ROM WiFi BT

Seems previous log lines fixed by removing USB-receiver for wireless keyboard.
But there are new host log lines.

Found workaround at kernel.org: https://bugzilla.kernel.org/show_bug.cgi?id=215496#c22
Is it possible to implement it in HAOS?

The people tried:
  [connection]
  wifi.powersave = 2

Please try if this also works to you.


And, please also try below two ko options, and do cold reboot.

rtw88_core
  disable_lps_deep=y
rtw88_pci
  disable_aspm=y

UPD: Trying to do that with HAOS configuration: https://github.com/home-assistant/operating-system/blob/dev/Documentation/configuration.md

[vturekhanov]

Closed this as this is really not an HAOS issue.
