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,
