Created attachment 1894842 [details] Override nm-wait-online-initrd.service Description of problem: When doing a network boot, rescue or install, with: Server/x86_64/os/isolinux/vmlinuz Server/x86_64/os/isolinux/initrd.img the boot fails sometimes in dracut-initqueue: Warning: dracut-initqueue: timeout, still waiting for following initqueue hooks: Warning: /lib/dracut/hooks/initqueue/finished/devexists-\x2fdev\x2froot.sh: "[ -e "/dev/root" ]" Warning: /lib/dracut/hooks/initqueue/finished/kickstart.sh: "[ -e /tmp/ks.cfg.done ]" Warning: /lib/dracut/hooks/initqueue/finished/nm.sh: "[ -f /tmp/nm.done ]" Warning: /lib/dracut/hooks/initqueue/finished/wait_for_settle.sh: "[ -f /tmp/settle.done ]" ... Warning: Could not boot. then enter the emergency shell: systemd[1]: Starting dracut-emergency.service - Dracut Emergency Shell.. Version-Release number of selected component (if applicable): dracut-056-1.fc36 How reproducible: Not always: depends on the machine and the ethernet port. Steps to Reproduce: 1. Attempt a network boot using PXE and iPXE, rescue or install Actual results: The boot fails in emergency shell. Expected results: Normal boot. Additional info: This is due to dracut-initqueue starting too early, after nm-wait-online-initrd that uses "/usr/bin/nm-online -s -q -t 3600" that terminates before the network is ready. Excerpt from the journal that shows that: Jul 05 11:38:06 fedora systemd[1]: Finished nm-wait-online-initrd.service. Jul 05 11:38:06 fedora systemd[1]: Starting dracut-initqueue.service - dracut initqueue hook... ... Jul 05 11:38:07 fedora kernel: IPv6: ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready ... Jul 05 11:38:09 xxxxxx NetworkManager[1011]: <info> [1657021089.8530] device (eth0): Activation: successful, device activated. Jul 05 11:38:09 xxxxxx NetworkManager[1011]: <info> [1657021089.8542] manager: NetworkManager state is now CONNECTED_GLOBAL I can provide the full journal if you need. I applied a workaround: override the nm-wait-online-initrd.service to replace nm-online by a loop waiting for the network to be really ready. See attached file: nm-wait-online-routes-gw.conf
