Hmmm...I ran my dsdt through the Intel ACPI decompiler/compiler on a 
linux box and was able to get some interesting input, at least I now 
know something more about ACPI.  I assume that this warning isn't 
causing any severe issues as it seems to be pretty common throughout the 
DSDT on my supermicro:
acpi.dsl  3213:                         Acquire (W627, 0x1388)
Warning  1103 -        Possible operator timeout is ignored ^

However the last few look very interesting and most probably are related 
to why my machine kind of dead locks when a PCI card is in the PCI-X slot:

acpi.dsl  4044:                 Field (IDE1, DWordAcc, NoLock, Preserve)
Error    4026 -                           ^ Access width is greater than 
region size

acpi.dsl  4046:                     MAP,    8,
Error    4027 -                       ^ Access width of Field Unit 
extends beyond region limit

acpi.dsl  4048:                     PCS,    8
Error    4027 -                       ^ Access width of Field Unit 
extends beyond region limit

acpi.dsl  4986:     Method (_WAK, 1, NotSerialized)
Warning  1079 -                ^ Reserved method must return a value (_WAK)


Any suggestions on how to approach supermicro with this information?
