A311D ethernet `cannot attach to PHY` error since 6.18.9 update

Hi there!

Since Kernel 6.18.9 (and now 6.18.10) kernel, I can’t use ethernet to connect to network.

So I try to restart reform-hw-setup manually with:

doas systemctl restart reform-hw-setup.service

And check kernel messages:

[ 3871.435604] meson8b-dwmac ff3f0000.ethernet end0: renamed from eth0

All seems to work there but network adapter is marke as DOWN with ip a. So I try to set it up then I have this error on dmesg:

[ 4029.204842] meson8b-dwmac ff3f0000.ethernet end0: Register MEM_TYPE_PAGE_POOL RxQ-0
[ 4029.211867] meson8b-dwmac ff3f0000.ethernet end0: cannot attach to PHY (error: -ENODEV)

From there I don’t know how to deep dive into debugging.

Thank you, I can confirm this issue. It looks like this when it’s working (on 6.17):

meson8b-dwmac ff3f0000.ethernet: IRQ eth_wake_irq not found

When it’s not working we get a dmesg which differs from the above like this:

Hi @josch thanks for replying so quickly! So waiting for a fix :slight_smile: .
