So I have to copy the messages manually from screen. I am now running a kernel with this options compiled in. One thing I noticed that may be relevant or not: The system is running with ACPI disabled using loader.conf. If I enable ACPI the device acpi0 fires ~10000 interrupts/s and there are three system processes acpi_task[0-2] that will consume ~25% when the system is idle. With ACPI disabled it does not show that behavoir. Markus
