Public bug reported:
When the resolution is changed on console and/or the Xserver is started,
the network/ethernet driver stops working.
This only happens in 205-generic
in 172-generic the same is fine.
lsb_release -rd:
Description: Ubuntu 20.04.6 LTS
Release: 20.04
uname -a:
Linux frg03 5.4.0-172-generic #190-Ubuntu SMP Fri Feb 2 23:24:22 UTC 2024
x86_64 x86_64 x86_64 GNU/Linux
Package: linux-image-5.4.0-205-generic
Symptoms:
When booting the system with 205 in normal mode (not recovery) the Xserver
starts in graphical mode, but the system has no network (no IP address
assigned) - any attempts to access network information such as "ip addr show"
"ifconfig" etc freezes the process in question.. attempting to reboot or halt
the system also freezes the process and hardreboot is necessary... no detailed
dmesg info is available since i cannot even sudo - (that accesses hostname
which freezes the sudo process)
When booting the system in 205 in recovery mode network works fine - until
graphics (nvidia) is loaded
this happens both with all driver packages from nvidia-driver-470 from ubuntu
repos and later nvidia drivers from nvidia PPA including nvidia-driver-570-open
current driver: Driver Version: 570.86.15, NVIDIA GeForce RTX 2080 Ti
(nvidia-driver-570-open [570.86.15-0ubuntu1])
when booting with linux-generic-172 the system works fine (both graphics and
network)
I can not make any statement w.r.t. kernel versions between 172 and 205 -- the
regression might have been introduced with anything in between -- this is the
only 2 versions i have currently installed.
