Hi
The reporter confirmed that
options rtw88_pci disable_aspm=1
works. In the light of
https://bugzilla.kernel.org/show_bug.cgi?id=206411#c11 and the
upstream commit 68aa716b7dd3 ("rtw88: pci: disable aspm for platform
inter-op with module parameter") this is probably a this time the best
one can do.
The commit reads:
rtw88: pci: disable aspm for platform inter-op with module parameter
Some platforms cannot read the DBI register successfully for the
ASPM settings. After the read failed, the bus could be unstable,
and the device just became unavailable [1]. For those platforms,
the ASPM should be disabled. But as the ASPM can help the driver
to save the power consumption in power save mode, the ASPM is still
needed. So, add a module parameter for them to disable it, then
the device can still work, while others can benefit from the less
power consumption that brings by ASPM enabled.

[2] Note that my lenovo T430 is the same.
