Subject: [ACPI Debug] String: Length 0x0F, "Entering RTMP()"

Hi,

2.6.9-rc2 is throwing a lot of these errors on my system:

[ACPI Debug] String: Length 0x0F, "Entering RTMP()"
[ACPI Debug] String: Length 0x0F, "Entering TIN2()"
[ACPI Debug] String: Length 0x0F, "Existing RTMP()"

About 450 of these three lines repeated so far, seem to get one every 5
seconds or so. Box is an Athlon64 solo, let me know if you want more
info (and what).

These are due to debug statements in your BIOS AML code.
The Linux AML interpreter recognizes them and sends
them to the console.

Start by checking that you're running a production BIOS.

echo 0 >/proc/acpi/debug_level should make them go away.

cheers,

That seems to be normal. These are debug prints from ACPI BIOS.

3 lines of dmesg every 5 seconds isn't quite optimal... But Len already
guided me to the acpi debug disable, which shuts it up.
