Raspberry pi 3B USB boot ok but hangs during reboot

Creating a bug report/issue

I have searched the existing open and closed issues

Required Information

DietPi version | G_DIETPI_VERSION_CORE=9 G_DIETPI_VERSION_SUB=12 G_DIETPI_VERSION_RC=1 G_GITBRANCH='master' G_GITOWNER='MichaIng'
Distro version | bookworm 0
Kernel version | Linux DietPi 6.12.20+rpt-rpi-v8 #1 SMP PREEMPT Debian 1:6.12.20-1+rpt1~bpo12+1 (2025-03-19) aarch64 GNU/Linuxl
Architecture | arm64
SBC model | RPi 3 Model B+ (aarch64)
SD card used | USB 3 drive connected to usb2 port

Actual behaviour

This is something that recently pops up. When I reboot the system (reboot or shutdown -r now), I have to physically go there and powercycle. Then it boots up correctly.

When I hook it up to a monitor when doing a reboot, the screen turns completely black the usb disk light goes out.

When I turn off the pi, unplug it and just wait a couple of minutes, it has no problem starting up. So it is not due to delay issues in booting up.

Is there anything else I can try to resolve this?

Extra details

I have enabled the persistent logging that I found in other posts and this is the shutdown cycle when I reboot:

Hmm, the shutdown cycle looks right until the very last possible log entry when journald is killed (as intended). There are no logs of a next hanging startup cycle, is it? So looks like it then hangs after journald is stopped or before it starts back up at boot. Can you estimate from LEDs or maybe HDMI output whether it is at shutdown or next startup?

Vidar · 21 April 2025 14:52

When I press reboot while attached to a screen, the screen disconnects (No HDMI image). And the disk lights blinks a couple of times and then stop.

There are indeed no logs of starting up twice if I do that.

Not sure at this point how to even debug . Maybe has to do with USB boot and maybe caused by recent kernel or bootloader update. Could be tested with latest RPi OS and, if same happens, reported at their forum or GitHub pages.
