Occurs with: 5.15.4-051504-generic and earlier 5.15 mainline ( https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.15.4/) as well as liquorix flavours. Does not occur with: 5.14 and 5.13 (both with various flavours) Hi all, I'm experiencing a severe bug that causes the machine to reboot or freeze when trying to login and/or rise/shutdown a NIC. Here's a brief description of scenarios I've tested: Scenario 1: enp6s0 managed manually using /etc/networking/interfaces, DHCP a. Issuing ifdown enp6s0 in terminal will throw "/etc/resolvconf/update.d/libc: Warning: /etc/resolv.conf is not a symbolic link to /run/resolvconf/resolv.conf" and cause the machine to reboot after ~10s of showing a blinking cursor b. Issuing shutdown -h now or trying to shutdown/reboot machine via GUI: shutdown will stop on "stop job is running for ifdown enp6s0" and after approx. 10..15s the countdown freezes. Repeated ALT-SysReq-REISUB does not reboot the machine, a hard reset is required. =2D- Scenario 2: enp6s0 managed manually using /etc/networking/interfaces, STATIC a. Issuing ifdown enp6s0 in terminal will throw "send_packet: Operation not permitted dhclient.c:3010: Failed to send 300 byte long packet over fallback interface." and cause the machine to reboot after ~10s of blinking cursor. b. Issuing shutdown -h now or trying to shutdown or reboot machine via GUI: shutdown will stop on "stop job is running for ifdown enp6s0" and after approx. 10..15s the countdown freezes. Repeated ALT-SysReq-REISUB does not reboot the machine, a hard reset is required. =2D- Scenario 3: enp6s0 managed by network manager a. After booting and logging in either via GUI or TTY, the display will stay blank and only show a blinking cursor and then freeze after 5..10s. ALT-SysReq-REISUB does not reboot the machine, a hard reset is required. =2D- Here's a snippet from the journal for Scenario 1a: Nov 21 10:39:25 computer sudo[5606]: user : TTY=3Dpts/0 ; PWD=3D/home/user ; USER=3Droot ; COMMAND=3D/usr/sbin/ifdown enp6s0 Nov 21 10:39:25 computer sudo[5606]: pam_unix(sudo:session): session opened for user root by (uid=3D0) =2D- Reboot -- Nov 21 10:40:14 computer systemd-journald[478]: Journal started =2D- I'm running Alder Lake i9 12900K but I have E-cores disabled in BIOS.
