Recently added SATA 1TB (WDC WD10EADS-00P8B0 01.00A01) and installed RELEASE 8.0 thereon. When I boot to RELEASE 8.0 I find after some time, few minutes to rather more minutes the system just powers down without warning or any obvious cause. It seems to mostly happen when the system is relatively quiet. Suspecting the ACPI I added: hint.acpi.0.disabled=1 to loader.conf. I then found RELEASE 8.0 would not boot -- or at least it was unable to mount root. I get a "mountroot>" prompt but this seemed not to accept anything I could think of, and "?" to list available targets yielded nothing. Rebooting and overriding this with option 2 (enable ACPI) in the boot menu took me back to a bootable but fragile system. Changing the loader.conf entry to: debug.acpi.disabled=all had the same effect as the hint.acpi.0.disabled=1. I then thought to be somewhat selective with debug.acpi.disabled and intended to try: debug.acpi.disabled=acad button cpu lid thermal timer video only now as I write this I discover I actually entered: debug.acpi.disabled=acadbutton cpu lid thermal timer video Now the RELEASE-8.0 booted but remained fragile. I've repaired this last entry and will proceed to try it. Meanwhile I feel I am fumbling about in the dark without sufficient (or any real) knowledge of the range of tasks performed by ACPI. Is my guess that I have an interaction problem between ACPI and RELEASE-8.0 a reasonable one? Where can I go from here? The system uses a Gigabyte GA-M55SLI-S4 mother board and the prcessor is AMD Athlon(tm) 64 X2 Dual Core Processor 5600+ Please offer suggestions or comments. Malcolm Kay
