 Giorgos,
 
 You're right. Although this report is faked, problem reported here is quite different --
 with ACPI_DEBUG but without DDB, produced acpi.ko has unresolved symbol:
 AcpiDmDumpMethodInfo. Some #ifdef's are probably missing.
 
 cognet@ suggested to let njl@ know about it. Thus, I'm putting him in CC.
 Once this bug is fixed, I'll close my PR.
 
 Thanks,
