Hmmmmm. Can you get the output > of 'devinfo -ur' with ACPI enabled? Also, you can maybe try setting > 'debug.acpi.disabled=sysres' from the loader. Unfortunately, it's getting even more puzzling now. :-/ When I set debug.acpi.disabled=sysres in the loader, I no longer get the resource allocation failure, thus ahc0 correctly gets the 0xde00 IO address range. Nevertheless, the boot hangs by the time when it wants to detect the disks. When I don't set debug.acpi.disabled=sysres, I'm back at the resource allocation failure. The only way to boot FreeBSD 8 is to disable ACPI. Are you interested in the devinfo -ur output from the FreeBSD 6.2 boot CD-ROM? I didn't spot anything interesting in it, but alas forgot to save it from the serial console link into a file. -- cheers, J"org .-.-. --... ...-- -.. .
