Public bug reported: The system fails to reboot, during the kernel boot process it hangs with the following red error
Timed out for waiting the udev queue being empty. Begin: Loading essential drivers ... done. Begin: Running /scripts/init-premount ... done. Begin: Mounting root file system ... Begin: Running /scripts/local-top ... done. Begin: Running /scripts/local-premount ... [ 120.832745] Btrfs loaded, zoned=yes, Scanning for Btrfs filesystems <system freezes> About 2 minutes later, kernel panic. The system will boot normally if powered off fully first. I have compiled kernel 6.8.8 using the same config and that solves the problem, however the Ubuntu -generic kernel does not work as described.
