I just (yesterday) cvsup'ed and rebuilt world/kernel, and I've noticed some changes. I noticed that the 'cx supported' has changed: Now: hw.acpi.cpu.cx_supported: C1/1 I'm not positive what it was before, but I remember a C3 and a C4 I believe - or am I hallucinating again? Also, I no longer get any sysctl's for acpi video - which was working flawlessly (allowing me to close the lid on my laptop and have it turn off the screen) before yesterday. It has been a little over a month since rebuilding the world/kernel, so a lot has changed I'm sure.. Not sure if this is related or not, however my machine has locked up pretty hard 3 times since then, definitely not normal. Two of those times, I believe the cpu fan went into overdrive after a short time of being locked.. Here's some info for those who might be able to help: I'm building acpi and acpi_video into the kernel now - I've also tried it via modules, same result. This is on a Dell Latitude D600 (BIOS A08). $ sysctl hw.acpi hw.acpi.supported_sleep_state: S1 S3 S4 S5 hw.acpi.power_button_state: S5 hw.acpi.sleep_button_state: S1 hw.acpi.lid_switch_state: NONE hw.acpi.standby_state: S1 hw.acpi.suspend_state: S3 hw.acpi.sleep_delay: 1 hw.acpi.s4bios: 1 hw.acpi.verbose: 1 hw.acpi.reset_video: 1 hw.acpi.cpu.throttle_max: 8 hw.acpi.cpu.throttle_state: 8 hw.acpi.cpu.cx_supported: C1/1 hw.acpi.cpu.cx_lowest: C1 hw.acpi.cpu.cx_usage: 100.00% [snip] dmesg and other info available on request.. Thanks!
