Hello Eric, thank you for filing this and for helping to improve Ubuntu. The version info is just what we needed to begin a kernel bisect, so thanks for that!
I've got the first test kernel ready for you here: https://people.canonical.com/~tswhison/bugs/2097885/0001-c12ae44.tar.gz Please try it out and let me know the status, whether good or bad. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/2097885 Title: Network driver freezes when nvidia driver is loaded on 205-generic Status in linux package in Ubuntu: New Bug description: 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.
