We've seen this before, I think this is a duplicate. If _OSC is called with an
Arg2 > 1 (which it is under Linux), then the while loop below will be executed
more than once. On the second iteration, an attempt is made to create the CAPB
buffer field a second time, which results in the failure seen.
Method (_OSC, 4, NotSerialized)
{
Store (Arg2, Local0)
Multiply (Local0, 0x04, Local1)
Name (BUF1, Buffer (Local1) {})
Store (Arg3, BUF1)
Store (0x00, Local1)
Store (0x00, Local2)
While (Local0)
{
Multiply (Local1, 0x04, Local2)
CreateDWordField (BUF1, Local2, CAPB)
If (Arg2)
{
And (CAPB, 0xFFFFFFFC)
Or (CAPB, 0x00)
}
Else
{
}
Increment (Local1)
Decrement (Local0)
}
Return (BUF1)
}
