See 'systemctl status systemd-udev-settle.service' for details. Starting Activation of DM RAID sets... [ ] (1 of 2) A start job is running for Activation of DM RAID sets (..min ..s / no limit) [ ] (2 of 2) A start job is running for Monitoring of LVM2 mirrors, snapshots etc. using dmeventd or progress polling (..min ..s / no limit) System is a Fedora 34 with all updates applied. Two other similar systems with AMD CPUs (Ryzen 4750G + 3400G) this does not happen and boots fine. The system where it does not boot has an Intel Xeon E3-1285L v4 CPU. All of them use a dm_crypt root filesystem. Any idea which patch I should drop to see if it boots again. I already dropped [PATCH 5.13 743/800] ASoC: Intel: sof_sdw: add quirk support for Brya and BT-offload and I just see that this one should also be dropped: [PATCH 5.13 768/800] hugetlb: address ref count racing in prep_compound_gigantic_page Will still need to test this.
