I found the HIGH_TABLES bug on the DBM690T.
The K8 HIGH_TABLES code places these tables in UMA video memory. Of course that memory is cleared by some payloads and operating systems.
However, if I fix that, Linux still crashes during boot because it only sees 32 MB instead of 2 MB RAM.
If I disable high tables completely, Linux complains about corrupt ACPI tables and other stuff.
Has the tables code been tested recently if it works even in the case where we don't want high tables?
