 You are sure that things work if you do not enable acpicpu(4)?
 
 Few things:
 
 a Can you further build a kernel with DIAGNOSTIC to rule out anything obvious?
 
 b Can you install sysutils/dmidecode, run it, and post the output? If we do
   not manage to fix this, the last resort is to add a quirk for this laptop.

 Given that no errors are now printed at runtime, I think the above are
 because acpicpu(4) should attach before acpitz(4), as the latter may
 reference, within the firmware AML, some things for the passive cooling.
 
 To put this differently: as the loading of acpicpu(4), or running the ACPI
 methods it runs, typically means that the ACPICA interpreter loads
 additional tables dynamically, it is natural that we get AE_NOT_FOUND from
 acpitz(4) because those things are not in the namespace yet.
