System updated to 6.1-PRERELEASE (I think) and works well. With one brute hack even 7.0-CURRENT works with ACPI - original error, panic: acpi_pci_update_device: deleting alive child acpi_sysresource1 can be removed by commenting first part of acpi_pci_update_device function in dev/acpica/acpi_pci.c file - code conditionally evaluated when child != NULL. After commenting it out system boots with ACPI and works. I would like to get some hints on what to look for, so I can at least understand why this code fails, what should it be doing. I have no knowledge on ACPI code, so any hint is appreciated. Regards, Milan
