Hi Since yesterdays pacman -Syu I'm unable to boot my system the usual way. My observation on that is the following. In early userspace the USB port's power gets cut for around a second which is indicated by the LED of the external drive I'm booting from. Therefore - as I further assume - recognition of the drive gets lost and decrypting and mounting of root is not possible. When I (un)plug the drive both actions get recognized as such but the device(s) don't get registered. I already guessed and tried to 1. reinstall syslinux bootloader, 2. (realize the power cut and) downgrade kernel, 3. downgrade (lib)systemd and 4. mkinitcpio from a chroot and reboot between each of the steps. Nothing of that helped. I will attach a grep of my pacman.log to show which pkgs where upgraded. There were no errors logged. I will happily provide any further information that might help directing me towards debugging and fixing that problem. Getting rid of the intermediate USB gets me rid of the described problem which is obviously no permanent solution. Thanks a lot. basti
