Yes, thanks!

I still use a Soekris Net6501-70 board. It shows the following errors when
ACPI is enabled:

Firmware Error (ACPI): A valid RSDP was not found (20200430/tbxfroot-369)
[...]
ACPI: Table initialisation failed: AE_NOT_FOUND
ACPI: Try disabling either ACPI or apic support.

It works fine without ACPI so I removed it. I need a custom kernel
anyway (the kernel panics without 'device atpic').
