------- Comment #27 from [EMAIL PROTECTED]  2008-01-17 16:00 -------

I have an issue with:

if (data.irq.descriptor_length == ACPI_DESCRIPTOR_4_BYTES)

If the field is named "length", I think that it should hold the actual length
of the descriptor, not an encoded length. If the length is indeed a flag, the
field should be:

if (data.irq.flags & ACPI_DESCRIPTOR_4_BYTES)

Otherwise, the name "length" is misleading and could lead to bugs later.

The options for the StartDependentFunctions are length 0 and length 1, so it
may be best to simply use the actual length, otherwise we end up with flags
like this:

ACPI_DESCRIPTOR_IRQ_3_BYTES
ACPI_DESCRIPTOR_IRQ_4_BYTES
ACPI_DESCRIPTOR_SDF_0_BYTES
ACPI_DESCRIPTOR_SDF_1 BYTE
