I was setting up two new servers today and noticed that they both were not recognizing the HT cpus. I enabled ACPI, rebooted, and now they show up. This appears to be a new thing in 2.6.14 as my 2.6.13 box sees the HT cpus without ACPI. Here's my working config, though you may be able to strip it down some more. # Power management options (ACPI, APM) # ACPI (Advanced Configuration and Power Interface) Support CONFIG_ACPI=y CONFIG_ACPI_AC=y CONFIG_ACPI_BATTERY=y CONFIG_ACPI_BUTTON=y CONFIG_ACPI_VIDEO=y # CONFIG_ACPI_HOTKEY is not set CONFIG_ACPI_FAN=y CONFIG_ACPI_PROCESSOR=y CONFIG_ACPI_THERMAL=y # CONFIG_ACPI_ASUS is not set # CONFIG_ACPI_IBM is not set # CONFIG_ACPI_TOSHIBA is not set CONFIG_ACPI_BLACKLIST_YEAR=0 # CONFIG_ACPI_DEBUG is not set CONFIG_ACPI_EC=y CONFIG_ACPI_POWER=y CONFIG_ACPI_SYSTEM=y kashani -- gentoo-user@gentoo.org mailing list
