Reboot stuck in u-boot while scanning USB bus

raspberrypi3
#1

Hi!

I am experimenting with rebooting my devices once a day, as a guarantee against memory leaks.

This morning the reboot had failed. The device was reported as offline, and no output was available when I connected to the serial port.

When rebooting from the container I use this Python snippet:
proc = await asyncio.create_subprocess_shell(
‘’‘DBUS_SYSTEM_BUS_ADDRESS=unix:path=/host/run/dbus/system_bus_socket \
dbus-send \
–system \
–print-reply \
–dest=org.freedesktop.systemd1 \
/org/freedesktop/systemd1 \
org.freedesktop.systemd1.Manager.Reboot
‘’’
)

To debug the issue, I connected to the serial port and did several “reboot” commands in the host OS. After several reboots my device got stuck I U-Boot, at “USB0: scanning bus 0 for devices…”

My Raspberry 3B+ has an FDTI USB-to-RS232 device connected, which might be relevant.
BalenaOS version is at VERSION=“2.31.0+rev1”

Does anyone know what’s wrong with my system?
