Complete system freeze during print, happening randomly

[ropa26]

Hi,

I have the CB1 on a Manta M8P board. Sometimes I can print perfectly fine, but sometimes during longer prints the printer stops and the system completely freezes. I cannot use the display, and network connectivity is also gone.

First I thought it is due to high temperatures, so I added a cooling fan to the board. CB1 board temperature during print is 58°C.
Then I thought it is due to WiFi driver issues, so I disabled WiFi and instead used the LAN connection. But the freeze still happens.

In the logs (syslog, kern.log) I don't see any messages from before the freeze, so I cannot debug the problem further.

I would appreciate any help or ideas on how to solve it or where the issue could be.

Thanks!

System information:

• Voron 2.4 printer
• CB1 firmware version: v3.0.0-25.02.0-trunk rolling
• Kernel: 6.6.66-vendor-sunxi64

I installed version 3 minimal and it freezes when I try to install kiauh

Same thing here. Random system hangs on 3.0.0 image. Using together with Ender 3 v3 se. It can work without issues for many hours and then just becomes unresponsive in any way until hard reset.

Since previous post I switched to 2.3.4 (using same version of klipper) and no hangs ever occurred during this period
