A cursory glance at your ASL shows nothing particularly amiss. It's very similar to my laptop (T23). > I tried compiling a version of the kernel with the ACPI_DEBUG option > listed in NOTES, but buildkernel dies This was fixed on Sept 21 so cvsup and recompile. Set hw.acpi.verbose=1 in loader.conf to get more messages. To debug this, please boot a newer kernel with the ACPI_DEBUG option with the following options in loader.conf: debug.acpi.layer="ACPI_ALL_COMPONENTS ACPI_ALL_DRIVERS" debug.acpi.level="ACPI_LV_FUNCTIONS" You'll get spammed with way too many messages on boot but just ignore these. Then do shutdown -p and log the printed messages (hopefully you have a serial console). I'll map the debugging tunables to a sysctl since it would be better if you could just set this just before testing rather than for the full boot. -Nate
