Letux Kernel

Issue 953: Pyra: Locks up on reboot (every kernel version)

Reported by Michael Mrozek, Nov 9, 2022

On every kernel version (we also tried the latest 6.10), the Pyra 
locks up when you try to reboot it.

Shutdown with power off and powering it on again works, but after a 
reboot, you need to do a hard power off, otherwise it will not boot 
up again.

The last visible log entry is:
[  394.101558] reboot: Restarting system

We're not sure whether it's Kernel or SoC locking up at the end or 
the bootloader after the restart because something is not setup 
properly, but we do know it's a hard lockup.

can not confirm / repeat.
So needs deeper analysis. If possible, provide a bootable SD image 
showing this effect.

Oh, so it doesn't happen with Letux rootfs?
It happens with the Pyra OS.

It can be downloaded from here:

So it's either:

* Something in the Pyra kernel, bootloader or dtb config
* Something in the Pyra rootfs

Maybe a first step to figure out what part causes this would be to 
use the Pyra Bootloader / Kernel with a Letux rootfs (or the other 
way round), if that's not too hard.

letux-5.15.37 shows a similar effect on simple "poweroff". 
Systemd reports shutdown but LEDs keep blinking.
