Hi Salvatore,

> Can you please do check, if it makes a diffrence if you reboot into
  6.17.13-1 from a previous non-problematic state or if you do cold-boot
  into it?

By 'cold-boot,' I assume you mean a full shutdown and power-on.

The original crash happened on a warm-reboot.

I tried to reproduce the issue again by testing several cold boots and
several warm reboots to see if the bug can be reproduced. All 5
cold-boots (shutdown, wait 10s, power on) and 5 warm-reboots ('reboot'
command) did not recreate the problem.

I will keep using the system as-is for now, since it does not seem to be
unstable. But do let me know if there's anything else that I can test.
Thanks for your time.

Best regards,

Nguyễn Trần Phước Thành
