still no interface for mt76x2u wifi card

[zebul666]

I still can't get a wifi interface with a wifi card using the mt76x2 drive:

[code]kernel: page_pool_create() gave up with errno -22
kernel: mt76x2u: probe of 1-1.3:1.0 failed with error -22
[/code]

on a rpi3b using archlinux armv7h

But this interface works fine on a rpi0w using raspiOS lite (bookworm)
It has the same kernel 6.6.51+rptrpi-v6 than archlinuxarm

So there is no reason that does not work on archlinuxarm and rpi3b ?

Not sure, is the mt76x2 module loaded (lsmod | grep mt76)? You can also try the RPi specific kernel which is linux-rpi and report back.

oh yes sorry. I am using the 6.6.51-3-rpi (armv7h) (not upgraded yet to the latest one).

the complete log is:
[code]kernel: usb 1-1.3: new high-speed USB device number 7 using dwc_otg

and the module is loaded

[/code]

but I still don't have a new interface showing up

but with the same kernel aka 6.6.51-3-rpi but on aarch64, this is working

[graysky]

OK so this the linux-rpi armv7h kernel and the linux-rpi aarch64 kernel. It works on aarch64 but not on armv7h. I cannot explain that. Both kernels are compiled with the same module options. Could this be an upstream regression? Have you considered creating an issue against the kernel?

If I could have tested with bookworm on rpi3b, and it worked, I would have said, it does not look like a upstream kernel bug
