No response

eth0 is up

Actual behaviour

eth0 has no-carrier

Steps to reproduce

the ethernet cable is attached to monitor, which is connected via usb cable to lenovo dock, to which laptop is connected.

with void installer: eth0 is up
with my system: eth0 has no-carrier

relevant dmesg:

with XXX being the actual mac

$ ip link

i tried downgrading the kernel, linux-firmware, using dracut: same issue.

compared to installer, i'm using booster initramfs, booting from efistub

$ ls /var/service

DISK="/dev/nvme0n1"

Any ideas?

[dkwo]

the installer is void-live-x86_64-musl-20221001-base.iso

relevant difference

dmesg | grep eth0
...(some renaming)
[   27.661631] cdc_ncm 2-4.2.1.2:2.0 eth0: register 'cdc_ncm' at usb-0000:00:14.0-4.2.1.2, CDC NCM (NO ZLP), XXX

vs

dmesg | grep eth0 
...(same renaming)
[   11.346163] cdc_ncm 2-4.2.1.2:2.0 eth0: register 'cdc_ncm' at usb-0000:00:14.0-4.2.1.2, CDC NCM, XXX
[   17.590876] IPv6: ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready

[dkwo]

I'll try downgrading to 5.19.10 kernel.

[dkwo]

downgrading kernel, musl, removing hardened-malloc does not fix it.

[dkwo]

nor does it downgrading pciutils, usbutils, iputils, ethtool

[dkwo]

also useless: only enable services present in live-usb; reinstall -ff eudev with no changes in /etc.

[dkwo]

$ doas ethtool eth0

only differences being speed and link detection

[dkwo]

short of wiping luks/lvm, or installing grub (which both seem absurd), not sure what else to try :)

[dkwo]

a new live image from today (linux 6.1) also works, so I exclude any other downgradings.

[dkwo]

finally, the culprit is tlp

[dkwo]

add USB_DENYLIST="0bda:8153" to tlp.conf
