Red Hat OS Deployment on a Sun Blade X8400 Server Fails if ACPI Is Enabled (6442992)

By default, the Sun Blade X8400 Server CMOS settings have ACPI enabled, which will cause Linux installation to go into interactive mode.

Workaround: There are two options:

1. Specify the additional kernel parameter to the load command.

N1-ok> load server servername osprofile profilename ... kernelparameter pci=nommconf

This will not change BIOS settings. Hence, you need to specify this parameter each time you issue the load command.

2. Configure BIOS settings manually by disabling the MCFG table in ACPI configuration. This will change BIOS settings permanently.
