Using a debug kernel, the machine came up quickly with this LOR after the reboot:

This first one appeared at 13:22 (short after bootup).

ok, the next two LORs (similar to the first):


at 13:28 this one came into the logs:

At 16:55 I catched this message:

kernel: acpi: suspend request ignored (not ready yet)

A minute (or seconds?) the machine died and I did not get anything around that time into the logs. What's the reason for this ACPI message?

After bootup (reset key pressed by an operator), the machine brought this LOR:

lock order reversal:

My assumption: The LORs are somewhat pf related but are not related to the lockdown of the system. Am I correct? What might be reason for that ACPI message and may ACPI be a cause of the lockdown? What might be a possible cause for WITNESS and INVARIANTS being unable to catch whatever causes the freeze?

Thx

Volker
