[PixelatedVolume]

I’m having (maybe) the exact same problem. Can I see the output of your lsmod | grep rtw? I suspect in my case it’s being caused by improperly blocking one of the “core” modules, so I’m curious about what you have loaded.

EDIT: I see you put the lsmod output in your first post, sorry!

[PixelatedVolume]

My theory is that the problem has to do with an ambiguous definition for the function rtw89_alloc_ieee80211_hw. The “failed to allocate hw” line is produced by a failed call to it.

In your lsmod results, you have rtw89_8852ae and also rtw_8852a (as do I). Seems to me that this should be rtw89_8852a, but when I try to load it manually, I get a dmesg saying rtw89_core provides rtw89_alloc_ieee80211_hw, which is already provided by rtw89core. I’ve tried blacklisting rtw89core and then rtw89_core to stop this conflict, but it hasn’t had any effect.

Hey, will take a look in the morning. I see you are running a new kernel.

If you are running these drivers instead of the in-tree drivers, make sure you blacklist the in-tree modules. If you look at the Makefile in this repo and compare to the one's for rtw89 in the kernel source, you can see which to blacklist/keep.

I am on mobile and won't be back on computer until tmrw.

Hi, any updates? @stormbringer83
