Subject[WARNING WARNING] Lots and Lots of ACPI Debug Messages with 2.6.0-test9!
I got a rude wakeup call when I checked my logs after booting 2.6.0-test9. I have
gotten so many debug messages that the dmesg is overflowing with them!

Here is the current dmesg output:

Shutting down applications which access the ACPI subsystem via /proc (gkrellm
