Package: systemd
Version: 253.5-1
Severity: important
X-Debbugs-Cc: debian@undef.tools
Dear Maintainer,
On upgrade to systemd 253.5-1 the USB modem on my Librem5 stopped
working. This also occurs on 252.11-1 (testing) but not on 252.6-1
(stable) or 253-3 (previously available in unstable.
This only seems to happen in a very specific configuration:
* Librem5
* Booting from eMMC
* Using full disk encryption
* Using an on-screen keyboard such as osk-sdl to unlock the device.
Digging into the issue, it seems I can trigger it by adding an initramfs
script which will run `udevadm settle` in the initramfs. This itself
doesn't remove the USB device, but later in the boot the device will
disappear.
The following logs are found in dmesg:

If `udevadm settle` or the on-screen disk encryption keyboard is not run
in the initramfs the issue does not occur.
Rolling back to systemd 252-3 or 252.6-1 works around the issue. I
originally saw the issue on 252.11-1 but didn't report it as upgrading
to systemd from unstable (253-3) fixed the issue.
Additionally, using a keyfile such that running `udevadm settle` or
equivalent is not required works around the issue (though makes disk
encryption slightly pointless).
