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: ``` [ 28.890890] usbcore: registered new interface driver option [ 28.890948] usbserial: USB Serial support registered for GSM modem (1-port) [ 28.960264] input: Librem 5 Headphones as /devices/platform/sound/sound/card0/input5 [ 29.080045] option 1-1.2:1.0: GSM modem (1-port) converter detected [ 29.080766] usb 1-1.2: GSM modem (1-port) converter now attached to ttyUSB0 [ 29.091094] input: Librem 5 Headset Mic as /devices/platform/sound/sound/card0/input6 [ 29.092893] imx-hdmi sound-hdmi: snd_soc_register_card failed (-517) [ 29.107724] option 1-1.2:1.1: GSM modem (1-port) converter detected [ 29.277461] usb 1-1.2: GSM modem (1-port) converter now attached to ttyUSB1 [ 29.292653] option 1-1.2:1.2: GSM modem (1-port) converter detected [ 29.326085] imx-hdmi sound-hdmi: snd_soc_register_card failed (-517) [ 29.427883] usb 1-1.2: GSM modem (1-port) converter now attached to ttyUSB2 [ 29.457265] option 1-1.2:1.3: GSM modem (1-port) converter detected [...] [ 31.474866] usb 1-1.2: USB disconnect, device number 4 [ 31.475478] option1 ttyUSB0: GSM modem (1-port) converter now disconnected from ttyUSB0 [ 31.475542] option 1-1.2:1.0: device disconnected [ 31.482999] option1 ttyUSB1: GSM modem (1-port) converter now disconnected from ttyUSB1 [ 31.483071] option 1-1.2:1.1: device disconnected [ 31.507980] option1 ttyUSB2: GSM modem (1-port) converter now disconnected from ttyUSB2 [ 31.508439] option 1-1.2:1.2: device disconnected [ 31.552074] option1 ttyUSB3: GSM modem (1-port) converter now disconnected from ttyUSB3 [ 31.552146] option 1-1.2:1.3: device disconnected [ 31.552425] qmi_wwan 1-1.2:1.4 wwan0: unregister 'qmi_wwan' usb-xhci-hcd.4.auto-1.2, WWAN/QMI device ``` 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). -- Package-specific info: -- System Information: Debian Release: trixie/sid APT prefers testing APT policy: (500, 'testing'), (1, 'experimental') Architecture: arm64 (aarch64) Kernel: Linux 6.1-librem5 (SMP w/4 CPU threads; PREEMPT) Kernel taint flags: TAINT_CRAP Locale: LANG=C, LC_CTYPE=C.UTF-8 (charmap=UTF-8), LANGUAGE not set Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages systemd depends on: ii libacl1 2.3.1-3 ii libaudit1 1:3.0.9-1 ii libblkid1 2.38.1-5+b1 ii libc6 2.37-5 ii libcap2 1:2.66-4 ii libcryptsetup12 2:2.6.1-4 ii libfdisk1 2.38.1-5+b1 ii libgcrypt20 1.10.2-2 ii libkmod2 30+20230519-1 ii liblz4-1 1.9.4-1 ii liblzma5 5.4.1-0.2 ii libmount1 2.38.1-5+b1 ii libp11-kit0 0.24.1-2 ii libseccomp2 2.5.4-1+b3 ii libselinux1 3.4-1+b6 ii libssl3 3.0.9-1 ii libsystemd-shared 253.5-1 ii libsystemd0 253.5-1 ii libzstd1 1.5.5+dfsg2-1 ii mount 2.38.1-5+b1 ii systemd-dev 253.5-1 Versions of packages systemd recommends: ii chrony [time-daemon] 4.3-4 ii dbus [default-dbus-system-bus] 1.14.8-1 ii dbus-broker [dbus-system-bus] 33-1 Versions of packages systemd suggests: ii libfido2-1 1.13.0-1 ii libqrencode4 4.1.1-1 pn libtss2-esys-3.0.2-0 <none> pn libtss2-mu0 <none> pn libtss2-rc0 <none> ii polkitd 122-4 pn systemd-boot <none> pn systemd-container <none> pn systemd-homed <none> ii systemd-resolved 253.5-1 pn systemd-userdbd <none> Versions of packages systemd is related to: ii dbus-user-session 1.14.8-1 pn dracut <none> ii initramfs-tools 0.142 ii libnss-systemd 253.5-1 ii libpam-systemd 253.5-1 ii udev 253.5-1 -- no debconf information
