@Alf Usually the ACPI errors don’t actually cause a halt. See them as warning more than errors. Still you can ad noacpi
in the host settings as Host Kernel Arguments.
In that one picture you have rcu ...
errors after the ACPI warning. Those are really causing a problem/system halt! Other users report those on other systems as well and we are not sure how those can be fixed.
If I get you right you said you have used FOG 1.5.4 before and exactly those systems showing the problems did work fine with FOG 1.5.4, right?
