Shouldn't at least all error and warning messages be printed even if 
ACPI_DEBUG is off?

I collected all ACPI_DEBUG_PRINT (ACPI_DB_ERROR | ACPI_DB_WARN | 
ACPI_DB_INFO, ...) messages for discussion under:

ftp://ftp.suse.com/pub/people/trenn/acpi_messages/acpi_DEBUG_ERROR_messages
ftp://ftp.suse.com/pub/people/trenn/acpi_messages/acpi_DEBUG_WARNING_messages
ftp://ftp.suse.com/pub/people/trenn/acpi_messages/acpi_DEBUG_INFO_messages

The patch (2.6.11-rc5) attached provides another config, 
ACPI_DEBUG_LITE, that at least prints out ACPI_DB_ERROR | ACPI_DB_WARN 
messages.

It's probably cleaner to convert:

ACPI_DEBUG_PRINT (ACPI_DB_ERROR, ...)   -> ACPI_REPORT_ERROR (...)
ACPI_DEBUG_PRINT (ACPI_DB_WARNING, ...) -> ACPI_REPORT_WARNING (...)
ACPI_DEBUG_PRINT (ACPI_DB_INFO, ...)    -> ACPI_REPORT_INFO (...)

to show that messages, even if ACPI_DEBUG is disabled, without the need 
of another config variable.

Before I start on this one, I'd appreciate if someone of the Intel 
people could comment whether this will be accepted for mainline.

Thanks,
