Comment 15 for bug 58386

I have a Dell Optiplex GX270. When I grep the dmesg I get the error that this bug report shows.

I then did this:
~ sudo cp /proc/acpi/dsdt .
~ sudo iasl -d dsdt
~ sudo iasl -sa dsdt.ds

After it compiles I get this Warning:

dsdt.dsl 1052: Method (_S5D, 0, NotSerialized)
Warning 1097 - Unknown reserved name ^ (_S5D)

ASL Input: dsdt.dsl - 3213 lines, 108415 bytes, 1051 keywords
AML Output: dsdt.aml - 9858 bytes 394 named objects 657 executable opcodes

Compilation complete. 0 Errors, 1 Warnings, 0 Remarks, 257 Optimizations

I tried tracking down "Method (_S5D", but couldn't find anything. I get close but no cigar.
