kernel/acpi: Improve the disabling of Debug object dumping.
on a Lenovo S10 Intel Atom n270, i386, there is continuous output to console
[ACPI Debug] String [0x11] "Current temp is: "
[ACPI Debug] Integer 0x00000036
I am using GENERIC with this machine so ACPI_DEBUG should not be specified.
Thanks for reverting, now using master through

Revert "kernel/acpi: Improve the disabling of Debug object dumping."
I no longer have the [ACPI Debug] messages flooding the console on this machine.
Sorry, the patch is here: http://leaf.dragonflybsd.org/~swildner/acpi_enable_debug_objects.diff
I've mailed email@example.com for clarification about this issue, since it looks like a flaw in their code.
Output from debug objects should be disabled by default (via the AcpiGbl_EnableAmlDebugObject global which defaults to FALSE and which the commit made tweakable (without messing with the default)), but due to some issues in the way they check this global and how it interacts with the AcpiDbgLevel global, they get printed anyway.
I'll see what they have to say about it.
- Status changed from New to Closed
Closing this. On latest master (including http://gitweb.dragonflybsd.org/dragonfly.git/commitdiff/586fced21e39bbdac0482f742fdb13fdf39506cc) your box should no longer print Debug object output. The sysctl debug.acpi.enable_debug_objects can be used to toggle it.
